Abstract
A higher quality image can be presented in response to a resize action by using the resized image as a starting point for a progressive encoding scheme. A system that provided the image content can resize a copy of the original image in order to have a copy of the resized image. The system can encode a new image of the target size using a wavelet encoding algorithm, and can compare the resized version to one or more of the intermediate decoded versions produced by the encoding scheme. Upon finding a similar intermediate version, the server can provide the remaining transformation passes to be applied to the resized version previously provided. A correction pass can also be executed that applies a filter or post-processing algorithm to reduce the delta between desired output and the output from the transformation.
