ZYBO Z7 video processing demo: Sobel edge detection not works

[MHBagh]

Hi

I'm using ZYBO Z7020 and I want to implement Sobel edge detection. I found the C++ codes in documents of "ZYBO Z7 & Pcam 5C HLS Video Workshop", but it has some errors when I Run C Simulation in Vivado HLS 2019.1. It would be appreciated in advance if someone help me to fix it. My C++ codes and print screen of my Console and Error is attached.

Regards

edge_detect.cpp edge_detect.h edge_detect_test.cpp

Hello @MHBagh,
It seems that in the code all the Mats are defined as HLS_8UC3 (RGB Images). In the code, you are doing conversions between RGB and GRAYSCALE images before and after applying the Sobel operator.
Try to redeclare the input and output Mats of the Sobel operator (img1 and img2) as HLS_8UC1 and see if the assert succeeds.
