Abstract
A system for facilitating tone mapping is configurable to (i) generate an input image histogram based on one or more input images, the input image histogram comprising a plurality of bins, wherein each bin of the plurality of bins is associated with one or more pixel values and indicates a quantity of pixels that comprise the one or more pixel values; (ii) generate a target histogram based at least on the input image histogram; and (iii) generate an output image by using the target histogram to map pixel values of at least one of the one or more input images to corresponding pixel values in the output image.
Claims12
A system for facilitating tone mapping, the system comprising:
- one or more processors;
- and
- one or more hardware storage devices that store instructions that are executable by the one or more processors to configure the system to:
- generate an input image histogram based on one or more input images, the input image histogram comprising a plurality of bins, wherein each bin of the plurality of bins is associated with one or more pixel values and indicates a quantity of pixels that comprise the one or more pixel values;
- generate a target histogram based at least on the input image histogram by applying one or more smoothing operations to the input image histogram generated based on the one or more input images;
- and
- generate an output image by using the target histogram to map pixel values of at least one of the one or more input images to corresponding pixel values in the output image.
