I am using Vivado HLS 2018.3 along with xfOpenCV library v2018.3 for image processing. In the UG1233 (v2018.3) January 24, 2019, it says that there is a function named xf::crop() to crop ROI from Input image. However, the github repo of 2018.3 release doesn't have the same function in include/imageproc/xf_crop.hpp. I found the same function for v2019.1. However, this cannot be used as it has multiple dependencies on other files (I tried it though but no luck).
So either I would have to shift to 2019.1 version or use some other method to crop ROI from image. Kindly provide me if any idea regarding the same as I don't wish to migrate to new version currently.
