resize diff between java djl and python cv2 #3222

Does NDImageUtils.resize has the same result with cv2.resize? They all use bilinear by default. I got some diff between NDImageUtils.resize and cv2.resize

They are not the same. If you want to get the same result you should resize the Image object instead of resize NDArray use OpenCVImageFactory class

See this example: https://github.com/deepjavalibrary/djl/blob/master/examples/src/main/java/ai/djl/examples/inference/cv/SemanticSegmentation.java#L89
