As shown in Figure 9d, the green line is the manually labeled field boundary and the red line is extracted by the algorithm. The angle between the two lines is used as the criterion for judging the detection accuracy of the boundary line. Calculate the angle between two lines in the image coordinate system. Take the top left corner of the image as the origin, the horizontal axis as the X-axis, the vertical axis as the Y-axis. In this coordinate system, the angle between the red or green line and the X-axis can be calculated, and then the angle can be obtained. Count the angle between the red and green lines in the 50 paddy field pictures selected above, with an average value of 1.63 and a variance of 0.14()2. Therefore, the accuracy of the field boundary extracted by the proposed algorithm can meet the requirements of automatic navigation.
The pointer must be aligned even for zero-length slices. Onereason for this is that enum layout optimizations may rely on references(including slices of any length) being aligned and non-null to distinguishthem from other data. You can obtain a pointer that is usable as datafor zero-length slices using NonNull::dangling().
Fig. 9 shows a temperature controller (TC) in automatic mode. The MV1 (Input 1) trend in the bottom window is the output from the TC. The CV (output) trend in the top window is the process value (PV) of the TC. The controller setpoint is bumped automatically by the sequence. The data is completely closed-loop and there are discontinuities in the data set caused by time 16 periods when the TC is in manual and offline. The discontinuities can pose serious challenges to other currently practiced system identification methods, if the data set is not sliced or preconditioned. The discontinuities do not affect the SLIC-ID algorithm. In fact the discontinuities and nonlinearities (if any) are identified and isolated by the SLIC-ID algorithm while determining the true transfer function process dynamics.
Every bit-vector crate can give you an opaque type that hides shift/maskcalculations from you. BitSlice does far more than this: it offers you thefull Rust guarantees about reference behavior, including lifetime tracking,mutability and aliasing awareness, and explicit memory control, as well as thefull set of tools and APIs available to the standard [bool] slice type.BitSlice can arbitrarily split and subslice, just like [bool]. You can writea linear consuming function and keep the patterns you already know.
BitStore is the simpler of the two parameters. It refers to the integer typeused to hold bits. It must be one of the Rust unsigned integer fundamentals:u8, u16, u32, usize, and on 64-bit systems only, u64. In addition, itcan also be an alias-safe wrapper over them (see the access module) inorder to permit bit-slices to share underlying memory without interfering witheach other.
This parameter determines how bitvec indexes the bits within a single Tmemory element. Computers all agree that in a slice of T elements, the elementwith the lower index has a lower memory address than the element with the higherindex. But the individual bits within an element do not have addresses, and sothere is no uniform standard of which bit is the zeroth, which is the first,which is the penultimate, and which is the last.
The BitView trait implements .view_bits::() and.view_bits_mut::() methods on elements, arrays, and slices. This trait,imported in the crate prelude, is probably the easiest way for you to borrowmemory as bits.
BitSlice adds trait implementations that [bool] and [T] do not necessarilyhave, including numeric formatting and Boolean arithmetic operators.Additionally, the BitField trait allows bit-slices to act as a buffer forwide-value storage.
Iterators do not require that each yielded item is destroyed before thenext is produced. This means that each bit-slice yielded must be markedas aliased. If you are using this in a loop that does not collectmultiple yielded subslices for the same scope, then you can remove thealias marking by calling the (unsafe) method .remove_alias() onthe iterator.

If the first bit is matched, then an empty bit-slice will be the firstitem yielded by the iterator. Similarly, if the last bit in thebit-slice matches, then an empty bit-slice will be the last itemyielded.

Iterates over subslices separated by bits that match a predicate, givingup after yielding n times. The nth yield contains the rest of thebit-slice. As with .split(), the yielded bit-slices do not contain thematched bit.
Iterates over mutable subslices separated by bits that match apredicate, giving up after yielding n times. The nth yield containsthe rest of the bit-slice. As with .split_mut(), the yieldedbit-slices do not contain the matched bit.
Iterates over mutable subslices separated by bits that match apredicate from the back edge, giving up after yielding n times. Thenth yield contains the rest of the bit-slice. As with .split_mut(),the yielded bit-slices do not contain the matched bit.
This scans over self.windows(other.len()) until one of the windowsmatches. The search key does not need to share type parameters with thebit-slice being tested, as the comparison is bit-wise. However, sharingtype parameters will accelerate the comparison.
Like .starts_with(), the search key does not need to share typeparameters with the bit-slice being stripped. Ifself.starts_with(suffix), then this returns Some(&self[prefix.len() ..]), otherwise it returns None.
Like .ends_with(), the search key does not need to share typeparameters with the bit-slice being stripped. Ifself.ends_with(suffix), then this returns Some(&self[.. self.len() - suffix.len()]), otherwise it returns None.
src is the range of bit-indices in the bit-slice to copy, and dest is the starting index of the destination range. srcanddest .. dest +src.len()are permitted to overlap; the copy will automatically detect and manage this. However, bothsrcanddest .. dest + src.len()**must** fall within the bounds ofself`.
Calling this function with an over-long slice is library-levelundefined behavior. You may not assume anything about its implementationor behavior, and must conservatively assume that over-long slices causecompiler UB.
