  • Patent number: 9049448
    Abstract: Methods and systems for bidimensional video processing comprise preprocessing the video signal in horizontal and vertical dimensions of the video signal to reduce an amount of information of the video signal by low pass filtering the video signal and removing pixels to obtain an information-reduced video signal; expanding the information-reduced video signal by an expander process to produce an upconverted video signal; and comparing the upconverted video signal to the original video input to generate a support signal based on a difference between the original video signal and the upconverted video signal. Further embodiments include at least one of storing and transmitting the information-reduced video signal and the support signal; and during post-processing, processing and combining the information-reduced video signal and the support signal to generate a full information duplicate of the video signal.

  • Patent number: 8929446
    Abstract: A combiner processing system and a method of operating the combiner processing system are disclosed. In one embodiment, the combiner processing system is utilized for a support layer processing in a bit-rate reduction system that separates video data into a main layer and a support layer with separated encodings for the two layers for bit-rate reduction and data transmission efficiency. Preferably, the combiner processing system for the support layer processing is capable of processing repeat patterns, small high frequency details, and textual information contained in one or more images. Furthermore, in one embodiment, the combiner processing system for the support layer processing provides a motion vector detection on a full image reconstruction, a non-linear quantization which retains both textual information and small high frequency details, utilization of full combination motion vectors, and a separate processing path for textual information with an internal bit-rate reduction unit.

  • Patent number: 8831354
    Abstract: One or more systems and methods for edge-adaptive and recursive non-linear filtering of ringing effect on image or video data are disclosed in accordance with various embodiments of the invention. In one embodiment of the invention, a method for edge-adaptive and recursive non-linear filtering of ringing effect first involves detecting all edges within a process area of an image, including a direction of an edge slope and a value of an edge signal level. Then, if the process area is determined to be a “non-busy” area based on a “busyness” measure relative to empirically-defined threshold values, then an edge influence function subsequently determines whether to apply a de-ringing filter to a current pixel within the process area or not. Preferably, the de-ringing filter is edge-adaptive, non-linear, and recursive. The de-ringing filter can adjust the current pixel multiple times based on filter angles, adjacent pixels, and pixel transition levels.
