Hi , I just had an exercise writing the canny image detection algorithm without using the Edge function. I used imshow to present the following images # - original image # - gradient image after using the higher threshold # - non-maximum suppression of the higher threshold # - final image after the edge connecting using the lower threshold # after the non max suppression on it . # - the canny implementation of matlab but the results are too different. any ideas looking at my method ? Low Thresh = 0 High Thresh = 0.5 Gaussian sigma = 0.5 cheers > isn't it what canny does? the difference : > thank you. Despairy

Hi , I just had an exercise writing the canny image detection algorithm without using the Edge function.

I used imshow to present the following images

but the results are too different. any ideas looking at my method ?

Low Thresh = 0
High Thresh = 0.5
Gaussian sigma = 0.5

cheers

isn't it what canny does? the difference :

thank you. Despairy
