    Preparing Test data

    This repository contains extra data for the OpenCV library. Some code tests will be used, so you need to download it separately and arrange the path of the data

    Introduction to High Dynamic Range Images [HDR]

    HDR and LDR specific concepts, interested in their own reference;

    High-dynamic Range (HDR) images can provide more Dynamic Range and image details than ordinary images. According to LDR(Low-dynamic Range) images with different exposure time, The LDR image corresponding to the best detail of each exposure time is used to synthesize the final HDR image, which can better reflect the visual effect in the real environment.

    High Dynamic Range Imaging (HDR) with OpenCV

    Code run: input and output

    • Environment build in the blog post opencv-master4.5.1 Python example code to run tests (I) part 1 has been recorded;

    Run code 1:

    cd opencv/samples/python/tutorial_code/photo/hdr_imaging

python hdr_imaging.py --input /home/moli/project/six/pyOpenCVLearn/opencv_extra-master/testdata/cv/hdr/exposures/

Copy the code
