SYSTEMS AND METHODS FOR NON-LINEAR PROCESSING OF IMAGE FRAMES

摘要

Embodiments of the present disclosure include systems and methods for image processing for enhancing, e.g., photos, videos, and graphics representations. Particularly, some embodiments perform a histogram-based SMQT decomposition of various attributes in an original image. The SMQT decomposition of these attributes may then be used to create a look-up-table indicating how to modify pixel attributes in the same or a subsequent image so as to enhance the same or subsequent image. The results of the SMQT decomposition for each attribute may be interpolated based, e.g., on user preferences, to achieve a more optimal enhancement.

1. A computer-implemented method comprising:
obtaining a first image; generating a first histogram for a first attribute associated with pixels in the first image; generating a second histogram for a second attribute associated with pixels in the first image; generating a first Successive Mean Quantization Transform (SMQT) output using the first histogram; and generating a second SMQT output using the second histogram; and generating an interpolation look-up-table based at least in part upon the first SMQT output, the second SMQT output, and an interpolation parameter; and adjusting a pixel in a second image using the interpolation look-up-table.
