Abstract: Noise reduction in images is provided by performing a noise reduction step on blocks of pixels within a video-processing pipeline. The noise reduction step consists of applying a discrete cosine transform (DCT) to the block of pixels, quantizing the resulting DCT coefficients, and performing an inverse of the DCT to the quantized coefficients. The output of that noise reduction step is a block of image pixels similar to the input pixels, but with significantly less image noise. Because the noise reduction step can be performed quickly on small blocks of pixels, the noise reduction can be performed in real-time in a video processing pipeline.

Abstract: Methods, systems and apparatus, including computer programs encoded on computer storage media, for video content classification. A video content classification system classifies input video data frame by frame. The video content classification system performs customized discrete cosine transform (DCT) operations on each frame. The video content classification system then determines, based on results of the DCT operations, how much image information in the frame may be lost due to compression. If the loss is estimated to be below a threshold value, the video content classification system applies a high data compression ratio algorithm to compress the frame. Otherwise, the video content classification system applies a low data compression ratio algorithm to compress the frame. The video content classification system may generate output video data that is compressed differently frame by frame.

Abstract: An image processing apparatus which re-encodes encoded data, encoded with a pixel block having a predetermined number of pixels as a coding unit, while suppressing degradation of image quality, with a higher compressibility. For this purpose, when an encoded-image-data input unit inputs JPEG encoded data with an 8×8 pixel block as a coding unit, a redundancy estimation unit performs encoding on the encoded data, and sets an encoded data amount obtained by the coding, as a target code amount for a recompressor to perform coding in accordance with JPEG 2000 coding. The inputted encoded data is decompressed by a decompressor, and the recompressor generates encoded data in the previously-determined target code amount. The code amount control is performed by deleting the encoded data in bit planes in an order from a least significant bit plane toward a high-order bit plane.
