A consequence of this is that when shutting down, having only logged in one user, windows doesn't proceed with the shutdown request but instead stalls waiting for confirmation as "someone else is still using this PC" or somesuch; obviously no one else is using it as the only user to log in is the one logging out. You can "shutdown anyway" but if you're not paying attention and leave Windows to log itself off then it can hang waiting for the confirmation.
This appears to be what's happening, Windows makes ghost processes for the previous user presumably so when that user logs in login is faster; but our use (3 users in sequence) means these processes are always wasted.
I've tried all the various "things to try" that many people have posted here and elsewhere . . . all to no avail. No matter what I tried, the 'ghost' was always there IF I opened Excel full-screen (i.e. maximized). If I had foresight of mind to close Excel non-maximized, then when I'd re-open it things were fine (no ghost).
When I try to remove files, they sometimes become "ghost files" that are impossible to delete. These files disappear when the computer is restarted, but restarting my computer isn't always a reasonable solution because of rendering or other long-running tasks. Programs which frequently create and remove files (such as programs using lock files) often stop working because of these ghost files they cannot remove or replace. No program can open the file, either.
I would like to turn off this ugly mess whereby whenever you move the mouse at any speed other than a crawl, the mouse pointer leaves ghost trails at regular intervals. It happens everywhere in Windows and also in some games. I suspect Windows is not reporting all mouse movement. It happens on a regular system OR my quad i5 3470 on 144HZ monitor with 1000hz mouse polling rate 1600 DPI, with MarkC mousefix or whatnot. I have gtx770 GPU with all devices' and OS throttling disabled, i.e. max performance at all times. What causes this and can I get rid of this?
I have owned many vehicles in my 72 years of life. I have also had every vehicle I owned had it's windows tinted. The people and MGT. At Ghost Shield are some of the nicest and most professional group I have ever had the pleasure of working with. They helped me with a pickup and a return pickup when I couldn't procure a ride from a friend or family member.
Surrounded by water and guarded by an army of mosquitoes, ghost orchids are elusive. Lightning and torrential rain can discourage would-be photographers from getting their shot, and Wiley has encountered his share of storms. But even light rain can spell trouble for the ghost-orchid photographer: the blossoms are so delicate that they bounce with each raindrop or puff of breeze.
This particular edition is AMD's own reference version of the card, so the results below should probably be taken more as a baseline experience rather than an absolute best case scenario - especially now those third party models have started arriving on shop shelves with their superior coolers and overclocked boost speeds.
If I have some windows open, when I close the last one (i.e. Chrome) to go back to the desktop, I get a kind of ghost image on screen showing the last thing I saw on Chrome which lasts for about a second, then it goes away.
The new and fourth photo is probably the creepiest of all because as one El Pasoan poses outside the school, Ghost Girl is striking a pose in one of the windows mimicking the girl across the street, head-tilt included. The image was captured last summer as Sandra Quinonez took a picture of her cousin outside the school.
Quantum ghost imaging offers many advantages over classical imaging, including low photon fluxes and non-degenerate object and image wavelengths for imaging light sensitive structures, but suffers from slow image reconstruction speeds. Image reconstruction times depend on the resolution of the required image which scale quadratically with the image resolution. Here, we propose a super-resolved imaging approach based on neural networks where we reconstruct a low resolution image, which we denoise and super-resolve to a high resolution image. To test the approach, we implemented both a generative adversarial network as well as a super-resolving autoencoder in conjunction with an experimental quantum ghost imaging setup, demonstrating its efficacy across a range of object and imaging projective mask types. We achieved super-resolving enhancement of \(4\times\) the measured resolution with a fidelity close to 90\(\%\) at an acquisition time of N\(^2\) measurements, required for a complete N \(\times\) N pixel image solution. This significant resolution enhancement is a step closer to a common ghost imaging goal, to reconstruct images with the highest resolution and the shortest possible acquisition time.
Ghost imaging is an alternative image acquisition technique which utilises the correlations between two spatially separated fields of light to reconstruct an image of an object, therefore, photons that have not physically interacted with the object are used1,2. Individually each field cannot offer any image information on the object, however the correlations between them allows for the reconstruction of an image3,4. Ghost imaging was originally demonstrated as a quantum entanglement phenomenon5 and as a result of a spontaneous parametric downconversion (SPDC) process6, and recently shown with entanglement swapped photons7 and with symmetry engineered quantum states8. It was later shown that classical correlations can similarly be used in a ghost imaging experiment9,10,11. Quantum ghost imaging was initially thought to produce higher resolution images, however, it has been shown that in both quantum and classical cases images of almost identical quality are produced2,12. Advantageously, the use of quantum light allows for imaging at low light levels, demonstrating a higher signal to noise ratio and visibility12,13. Particularly, quantum ghost imaging is useful for biological imaging applications where it is beneficial to reduce the risk of photo-damage to light sensitive matter14.
A common ghost imaging goal is to reconstruct images with the highest resolution and the shortest acquisition times15, however, a limitation that ghost imaging faces is the inefficient imaging speed. Imaging speeds depend on the number of measurements needed to reconstruct the image which scales quadratically with the required resolution16. This imposes a practical limit on applications requiring high resolution images. Earlier raster scanning implementations were used5, which evolved to more timely methods using a single-pixel bucket detector and pre-computed binary intensity fluctuation patterns17, single-pixel scanning methods18,19 and Fourier single-pixel scanning methods20. The imaging speed remained unsatisfactory and so too did the number of measurements required to reconstruct the image21,22. Attempts to improve and enhance image quality and resolution focused on employing a pseudo-inverse ghost imaging technique via a sparsity constraint23, employing a Schmidt decomposition for image enhancement24, and imaging based on Fourier spectrum acquisition25. Deep-learning has recently gained a lot of interest due to robust enhancement and denoising capabilities in image resolution. Neural networks have been used in under-sampling the object and employing neural networks to enhance the reconstructed image26,27, performing Poisson noise reduction and using neural networks for image upscaling28, using neural networks to denoise the image29, using autoencoders as a self-supervised approach to enhance image quality30, and super-resolution imaging in the far-field with neural networks31.
In this work we outline a novel approach to producing super-resolved images in a quantum ghost imaging experiment. We experimentally reconstruct a low resolution image, which we denoise, and super-resolve without losing the finer details of the image. A lossless high resolution super-resolved image is achieved with fewer measurements. After implementing super-resolving neural networks we trained the networks to super-resolve images acquired from a complete ghost image reconstruction, i.e. N\(^2\) measurements where N \(\times\) N pixels is the image resolution. The N \(\times\) N pixel image is then super-resolved to a 4N \(\times\) 4N pixel image. Additionally, we implemented a reconstruction algorithm to suppress noise levels by leveraging noise-suppression characteristics from three different reconstruction algorithms. We start by describing our image reconstruction method, followed by our neural network description and experimental details, and finally present our results, where we demonstrate significant super-resolving capabilities. We believe that this novel approach to obtaining lossless super-resolved images will prove valuable to both quantum and classical ghost imaging experiments focused on obtaining high resolution images.
Figure 1 conceptually illustrates our all-digital super-resolved ghost imaging (GI) concept. The photon correlations necessary for ghost imaging, in our work, arise from a quantum source5,6,32,33. The required position correlations arise from the spatial entanglement of the signal and idler photons produced by a spontaneous parametric downconversion (SPDC) process using a non-linear crystal (NLC)34. Entangled photon pairs are spatially separated into two independent paths, one to illuminate the object (object arm) and one which is collected by a spatially resolving detector (reference arm). Our spatially resolving detection system is realised by displaying a series of binary patterns (masks) on a spatial light modulator (SLM), the projection is then collected by a bucket detector. The measured correlations then provide information on the similarity (or overlap) between the object and each mask. Scanning through a series of masks is a lengthy process which scales with the required resolution and is a great area of interest to the ghost imaging community26,27,28,33,35,36. Importantly, the patterns must form a complete basis to completely reconstruct the image. Once we have scanned through a series of masks and have reconstructed the image at a low resolution (low res), we then exploit artificial intelligence algorithms to denoise and super-resolve the image. This process produces super-resolved high resolution (high res) images without needing to measure at a higher resolution. Super-resolving neural networks allow us to measure at a low resolution while achieving up to 4\(\times\) super-resolving resolution enhancement.
