2020年9月9日 · Hello, I am stuck trying to figure out how to use the opencv demosaicing function. I have OpenCV 4.4.0 installed with CUDA support compiled in, and so far what I think I need to do is: Read in the raw image data Load in raw image data to a Mat object Upload the Mat data to a GpuMat (host to device upload) Demosaic Download the GpuMat data (device to host download) to a Mat object Display or ...

2014年8月4日 · Looking at cv:demosaicing I see that all of the Bayer2Foo methods require a source image has only one channel ...but the image VideoCapture provides already has three channels. Digging deeper into the VideoCapture sources, it appears that opencv's icvRetrieveFrameCAM_V4L immediately performs yuyv_to_rgb24 on any video source with a …

2016年1月14日 · 1)What is the difference between Imgproc.cvtColor(mat1, mat2, Imgproc.COLOR_BayerBG2RGB) and Imgproc.demosaicing(mat1, mat2,Imgproc.COLOR_BayerBG2RGB) when doing conversion from Bayer to RGB ? 2) In the above case, Imgcodecs.imwrite or BufferedImage's getRaster() is suitable for creating the image ? BufferedImage's getRaster() seems to be slower.

2016年7月27日 · However, at runtime with a 16-bit image I get the errror: OpenCV Error: Assertion failed (depth == CV_8U) in cv::cuda::demosaicing, file C:\opencv\opencv310\sources\modules\cudaimgproc\src\color.cpp, line 2132 Question: is this a bug or a fault in the documentation?

2013年1月18日 · It seems like your image isn't grayscale. convertTo doesn't change channels number, only depth. If you want to convert image to grayscale you should call cvtColor
