摘要:
A direction-adaptive image upsampling system and method using double interpolation is disclosed. Each of double interpolation (DI) units with different interpolation functions receives an input image and generates a corresponding double-interpolated image and an associated double-interpolated difference. A decision unit receives the double-interpolated differences from the DI units for deciding the DI unit that has an optimal interpolation around a pixel under process. An adaptive selector selects the double-interpolated image associated with the DI unit having the optimal interpolation as an output image.

A motion compensation apparatus and a motion compensation method are provided. The motion compensation apparatus comprises: a memory, a motion vector generator, a deviation calculator, a determining module, a selector and a motion compensator. The memory stores a plurality of frame encode information and a plurality of decoded frames; the motion vector generator generates a motion vector according to the plurality of frame encode information; the deviation calculator calculates a deviation data according to the motion vector and the plurality of decoded frames; the determining module determines a confidence level of the motion vector according to the deviation data; the selector selects a plurality of pixels from the plurality of decoded frames according to the motion vector when the confidence level is high; and the motion compensator compensates the plurality of decoded frames according to the plurality of pixels.

A super resolution (SR) method or system with database-free texture synthesis is disclosed. An input image is up-sampled to result in an up-sampled image. It is determined whether the input image possesses a smooth region. Edges of the up-sampled image are enhanced, and the enhancing edges step is bypassed if the smooth region has been detected. The enhanced or unenhanced up-sampled image is texture synthesized by taking the input image as texture example, thereby resulting in a synthesized image.

摘要:
In a method and system for writing a reference frame having multiple pixels into a reference frame memory, the pixels of the reference frame are sampled to obtain a plurality of representative pixels. A multi-bit pixel value of each of the representative pixels is divided into a number (N) of bit sections, each corresponding to one of a number (N) of different bit significance levels, based on a bit depth, where N is associated with the bit depth. The bit sections of the pixel values of the representative pixels having the same bit significance level are arranged together to form a number (N) of bit depth planes each including the bit sections that have a corresponding one of the bit significance levels. The bit depth planes are stored in the reference frame memory.
