Blur Image (Android)
Alpha Knows
CustomTarget(2, 2) is the trick. The lower the value the more the blur effect. Basically its used to shrink the image size. Then all you have to do is set the shrunk bitmap to your imageView. And most important is to set ScaleType of the imageView to CenterCrop.
I have clear images of cards vs blurry images of card. My task is to capture photo when the image is not blurry, as you can see from the description I need this code to run in real time on android device.
Although these transforms produce good output. They are badly slow. I need something which has speed similar to tflite object detection using android. Taking this logic in my mind my obvious step was to annotate images 1500(blurred cards) vs 1500(non blurry cards) and retrain ssdmobilenet model using tensorflow object detection api.
However when I exported the trained model to android I completely messy output, it appears as though the model has not learned anything from the data. My question is Is this problem solvable using object detection api as I mentioned above ? if yes where am I going wrong ? If no what are the fastest alternatives to detect blur in real time
One idea is to use a shallow (a handful of layers) CNN. Deep CNN's are good at detecting objects in images. Shallow networks focus on lower-level features, such as edges and textures and colors. So, my suggestion is to train a simpler network on a larger training set by training it on image patches rather than on full cards. If the majority of your patches are classifed as blurry, then you classify your whole card as blurry.
If you are looking to blur the background of your photo for an artistic, professional-looking portrait, most iPhones make this easy with the Camera app's Portrait mode. This feature is included in the iPhone SE (second generation and later) and most models from the iPhone 8 Plus or newer.
4. Swipe the slider to choose the amount of background blur you want. The smaller the number, the more pronounced the blur will be (for example, f 2.0 will generate a blurrier background than f 16).
Quick tip: You can adjust the blur after the photo is taken as well. If you take a picture in Portrait mode, open it in the Photos app, tap Edit, and then tap the f button at the top left. Use the slider to change the blur effect.
You don't have to rely on the iPhone's portrait mode to add blur to photos; there are apps available for iPhone and Android that let you add a blur effect. One of the easiest and most flexible apps with a blur tool is YouCam Perfect.
YouCam Perfect has several blur tools to choose from. There are options to blur the entire photo except for a shape (like a circular, elliptical, or rectangular) region that remains sharp, and another lets you use a brush to blur anywhere in the image. Here is how to use the app.
Well, this is one of the common issues which a smartphone user can encounter. But the good thing is, there are easy fixes to this problem. The key is to understand the root causes of your phone camera taking blurry images and then take the correct measures. This article will depict just that. We'll first comprehend your phone camera functionalities, and then dig into the reasons and solutions for blurry images from your android phone camera.
What helps a camera in setting up the focus is shifting the distance between the lens and the sensor. It involves a set of tiny lenses moving back and forth. This causes a change in how and where the captured light converges on the sensor. In simple words, these moving tiny lenses determine what is in focus and what isn't. Sometimes, this movement gets stuck, not allowing your phone to set proper focus.
2. Clean the Camera Lenses
The next thing you should try is cleaning the lenses of your camera setup. Use a soft, dry, and clean cotton cloth and wipe out the dust and dirt from both the front and back camera lenses.
Later, you can add a drop or two of lens cleaning fluid for better effects. Start from the outer part, and wipe the lens in a circular motion. Make sure you remove the oil, smudges, dirt, and dust properly.
3. Disable the Autofocus from Camera Settings
Many times a default setting in your camera app can cause blurriness in the front or rear camera blur. The next troubleshooting step for you is to disable the autofocus from settings.
Follow the below steps to do it:
- Open Camera App.
- Now put a long tap on the object in the focus.
- Hold it for a few seconds. It will lock the autofocus.
- Hopefully, the images without that autofocus will be better.
4. Restart Your Phone and Use the Camera App Again
This one is the basic yet most effective troubleshooting solution for Android camera app issues. What you need to do is to close the camera App completely (force close it if needed), and re-launch it. Then Restart your phone and try using the camera again. That might give your phone and camera app a fresh start, and help resolve app glitches.
6. Make sure you're not taking the picture through social media apps: Social media apps like Instagram simply screenshot the camera view when taking pictures. So chances are the picture quality will be poorer than the normal camera pictures.

I am trying to create validation of the image into my mobile application for different platforms(iOS, Android, etc.)Googled a lot I found some solutions and snippets but unfortunately they are not opaque for me.The idea is take a picture and validate it. For example attached image is not valid.
With one image I don't know if an image is blur or not. With two images you can compare values of bluriness but you need to define a region of interest. It's like when you take a picture do you want to see a blur backgound or a blur foreground?
Chiming in to add that I'm experiencing this issue too. RAW photos taken from my Sony A7IV are stuck on rendering when I use the new lens blur tool. Miraculously, I was able to export one photo and cannot replicate the steps I took on my iPhone 14 Pro (see below JPEG). I'm actually a little shocked to read that the developers were aware of a bug "that only affected large panoramic images" and still pushed this update to production. That's still a large enough use case to be a blocker in my opinion, especially considering this update through a bit of beta testing. I digress anyways, I'm hoping this gets fixed ASAP.
