Abstract:
A method for selecting an optimum subset of images from a larger set of images for optimal HDR image creation. For each of the set of images, an exposure quality map is computed by assigning, to each pixel of the image, an exposure quality value based on the pixel brightness value of that pixel. A suitable exposure quality function, typically reflecting the properties of the imaging device, is used for this purpose. Then, for each possible subset of images, the exposure quality maps for the images in the subset are combined using a max operation to generate a combined exposure quality map for the subset. An average pixel value of the combined exposure quality map of the subset is then calculated and serves as a quality score. The subset of images processing the highest quality score are used to generate the HDR image.
