edge Detection from scratch
- I performed a threshold enhancement on this algorithm, maybe the results is a little bit different from they should be.(less noises, but some lines are disjointed)
- put images with scripts in the same folder
marr.m is the edge detection algorithm
-n sigma
-filename lena
-extend .jpg
Gaussian_mask_pyramid.m create gaussian mask
-masksize
-sigma
main.m shows a way of using my "marr.m" to detect edges
it process those test images at once, lena,lena3, ucsb, up
note that
myConv.m implement convolution func
