Sample arrowed small specks are removed but the circled small cell is also removed. Perhaps next step would be to consider removing small AND no green marker (dark only) … WebB = imfilter(f, h, option1, option2,...) Description B = imfilter(A, H) filters the multidimensional array A with the multidimensional filter H.

How to process multiple images and produce output files?

WebJ = deconvlucy(I,psf,iter,dampar,weight) specifies which pixels in the input image I are considered in the restoration. The value of an element in the weight array determines how much the pixel at the corresponding position in the input image is considered. For example, to exclude a pixel from consideration, assign it a value of 0 in the weight array.

WebMar 23, 2024 · The filter we use to perform 2D convolution in Matlab requires a double datatype. That is why the gray-scale image has been further converted to double datatype gray-scale image. After that, a Gaussian convolutional kernel has been declared. Then, we declared a motion filter. Finally, these two filters have been convolved with the image.
