WebAug 6, 2015 · you create an image in RGBA format with your code, that's no problem. The problem is that OpenCV assumes BGR (A) images when saving the image or using openCV methods. Maybe you can use special libraries (png lib, jpeg lib etc) to save images directly in RGB (A) format, instead. WebJul 17, 2024 · When using OpenCV RAW to RGB conversion (CV_BayerBG2BGR), the image is displayed correctly but the image basic types are incorrect (elemSize & depth). Even writing the converted Mat to file and then loading it (rgb_path in code below), there is a discrepancy between the loaded rgb image and the converted rgb image, although both …

The reason the early developers at OpenCV chose BGR color format is that back then BGR color format was popular among camera manufacturers and software providers. E.g. in Windows, when specifying color value using COLORREF they use the BGR format 0x00bbggrr.
WebConvert a raw bayer image from mt9p031 at full size into a rgb (bgr) image for display and also save a jpg version. A 10 -> 8 bit down sampling is necessary to use the OpenCV built-in cvCvtColor (). The implementation of that algo is standard though and 10 bit could be conserved. This is just a quick hack for testing.
