Abstract:
1. A computerized encoding method comprising: determining a plurality of reference pixels and a plurality of predicted pixels for a set of connected pixels and a set of unconnected pixels in a reference frame and a frame being predicted, wherein the reference pixels are from the reference frame and the predicted pixels are from the frame being predicted for the set of connected pixels, and wherein the reference pixels and the predicted pixels are from the frame being predicted for the set of unconnected pixels; jointly transforming, by a computer, the sets of pixels into high-pass data using an orthonormal transform, wherein the high-pass data comprises high-pass coefficients for the set of connected pixels, and comprises residual values for the set of unconnected pixels, and wherein the plurality of reference pixels are reused in a joint transformation of another set of pixels, the another set of pixels including the plurality of reference pixels and at least one additional plurality of predicted pixels; and generating low-pass data using the plurality of reference pixels and the high-pass data, wherein the low-pass data comprises a low-pass coefficient for the set of connected pixels, and comprises an average pixel value for the set of unconnected pixels.
