Canny Edge Detection - Better results using the implemented method

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 :
