Description

I've been working on a project that needs to convert between several different types of images (BufferedImage, Mat, PIX), and I've noticed a strange issue when using the JavaCV frame converters, wherein the output image will be heavily skewed. For example, The original BufferedImage: buffimgtest vs. The Mat after conversion: mattest

Does anyone know what could be causing this?

Contributor guide

Research direction
Inspect the conversion code in frame converters, check the image type and channel order, verify that the Mat is created with correct parameters.
