Can anyone tell how to start from for pcam edge detection. I am done with camera working. But I do not understand what to do in the sdk where i can get the image data for processing and how I can send it to the hdmi ?

Hello @Muhammed Kawser Ahmed,
We currently do not have an example for software image processing for the Pcam project.
This HDMI Input/Output project does software processing, which could be used as a starting point, if you need software image processing. https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-z7-hdmi-demo/start

However, edge detection would be slow if implemented using the processor.

We also have the Embedded Vision Workshop, which guides you to create a demo which takes Pcam image data as input, processes it using a Sobel Edge Detection IP (which is created using Vivado HLS) and then sends it to an HDMI monitor. After completing the form on the website, a download should start containing a zip with the sources and the workbook for the workshop.

Note that this project is made to work with Vivado 2018.1, so I cannot guarantee it will work with other versions.

If you enjoy working with HLS, I would recommend you check out the Vitis Vision Library, which can be used with Vitis HLS 2019.1 and above.

Best wishes,
Eduard
