WebThus, if we multiply the original image by an amplification factor A before subtracting the low pass image, we will get a high boost or high frequency emphasis filter. Thus, Now, if A = 1 we have a simple high pass filter. When A > 1 part of the original image is retained in the output. A simple filter for high boost filtering is given by WebStarting in R2024a, imsharpen uses different color space conversion operations to sharpen RGB images. In R2024b and earlier, the imsharpen function performed the color space conversions using the makecform and applycform functions. Starting in R2024a, the imsharpen function performs the color space conversions using the rgb2lab and lab2rgb …

See this old blog post of mine for an explanation. Instead, use cv2.GaussianBlur(image, (0,0), 10.0) to let OpenCV compute the proper size of the kernel. But a sigma of 10 is way too large for this purpose, try 1 or 2 instead. –
