Title:
Automatic detection methods and equipment for image / video resolution and color subsampling
Document Type and Number:
Japanese Patent JP6335191
Kind Code:
B2
Abstract:
Methods and apparatus for automatic detection of image or video resolution from raw image or video data are provided by the present principles. The methods find statistical metrics in the image or video data based on a look-up table of potential resolution and subsampling combinations. The methods compute statistics comprising spatial correlation, temporal correlation, and variances in addition to considering color sampling and luminance levels. The methods determine the strength of correlation between portions of the raw image or video data and find the best match between the data and a plurality of possible resolution and subsampling formats.
