Write/design a "mattlab code" using "diffusion filter" to detect the lession from an (Breast Ultrasound image), which include steps:

1-Histogram equalisation.

2- Non-linear difussion.

3- Convolution of the breast image.

4- Median filtration.

5- Segmentation.

6- Labeling and morphological operations for the final edge detection.

- Instructions:

A- Write mattlab code (version2018 and below).

B- Use any Breast Ultrasound image.

C- Show figures for any step (figure out plots by step).
