ABSTRACT:
Methods and systems for image and video enhancement and data-loss recovery using wavelet transforms are disclosed. A wavelet transformed image is defined as multiple sections, where one section is the original image, and coefficients are estimated for each other section using information obtained from that section. An inverse wavelet transform on the wavelet transformed image obtains an enlarged image. For obtaining a high resolution video frame, one section is the original video frame, and coefficients are estimated for each other section using information from a lower level wavelet transform of a corresponding section of a past or future frame of the video sequence. For recovery of data lost from transmitted original data, the locality of the lost data is determined in lower and higher levels of a wavelet transform tree, and information at the locality in the lower and higher levels is used to estimate the lost data.
