Histogram Equalization
Equalization helps to extend the image histogram. After equalization, the gray level
range of the image is wider, which effectively enhances the contrast of the image.
Histogram
Normalization
It transforms histogram distribution of inputting image that is removed left and right-
end ratios into the specified histogram distribution.
Gray value range: The minimum value is the gray scale of the left end of the
histogram, and the maximum value is the right end of the histogram.
Standard Deviation
Normalization
It transforms the input image gray mean standard deviation to the standard deviation
gray level.
- Target mean value: it refers to the target mean value.
- Target standard deviation: it refers to target standard deviation.
Image Correction
Lens radial distortion is the general term of the inherent perspective distortion of the optical lens.
The image shape distortion that caused by optical lens inherent features (the convex lens merges
light rays and the concave lens diverges light rays) is divided into barrel distortion and pincushion
distortion. This function can correct these two kinds of distortions, as shown below
