mam please send the code because in video .... code is not clearly seen by eyes .... or upload 720p please mam

Superb explanation ma'am thank you....... upload more videos on image processing

superbly explained!!!

First one to like........ Amazingly explained...... Great

Good explanation but commands are not visible

Simple yet effective!!!!

Thanks Dr.Deepa. Very useful

Useful mam

mam if we execute a program it shows the error in the line c=edge(a,'roberts');it shows same error for all the others also.kindly help me to rectify it .

It is hard to follow because the font is too small

Any pdf of this content

Useful

Can you upload videos about autism detection and classification?

Please, I want the code

Mam give the code link

Maam please send the code

Dear MAAM I am a PhD student I would like to collaborate on a paper, I would guarantee to publish this work with in a month in a good journal SCI indexed. Please let me know if u r interested

mam please send the code because in video .... code is not clearly seen by eyes .... or upload 720p please mam
