Web7 de dez. de 2015 · Merge exposures into HDR image In this stage we merge the exposure sequence into one HDR image, showing 2 possibilities which we have in OpenCV. The first method is Debevec and the second one is Robertson. Notice that the HDR image is of type float32, and not uint8, as it contains the full dynamic range of all exposure images. Webimageio.v2.imread. #. imageio.v2.imread(uri, format=None, **kwargs) [source] #. Reads an image from the specified file. Returns a numpy array, which comes with a dict of meta data at its ‘meta’ attribute. Note that the image data is returned as-is, and may not always have a dtype of uint8 (and thus may differ from what e.g. PIL returns).
