Answer 1

[Image Analyst]

They are all FIR filters, but of various effects. The top one blurs the image. The middle one is a bit weird, but is probably a valley detection or curved line detection filter. The bottom one is clearly an edge detector.

Please accept the answer if it answers your question(s).

I accepted the answer on filters but I also need the main program (main) in addition to the function you gave me does not work otherwise. thank you very much. i don't understand this things

I don't know what main program you're talking about. If you want, you can call those filters by making up the 3x3 arrays and calling imfilter() or conv2().

kernel = [2,2,2;2,14,2;2,2,2]/30;
outputImage = imfilter(inputImage, kernel);
