摘要： A fast text/graphics resolution improvement algorithm is based on boundary parameterization and uses chain-code table look-up. Given an input representation containing text/graphics objects, the boundary of each object is traced, parameterized, smoothed, and subsequently rendered. Instructions for the critical operations are stored in one or more pre-computed look-up tables (LUTs) which is/are accessed during on-line operation, resulting in an algorithm that is fast and computationally inexpensive with low memory requirements. A very flexible framework is presented which can be utilized in a variety of applications requiring resolution improvement.

摘要： A de-noising algorithm that obtains an estimate of a noise-free portion of a noise-containing digital signal by applying a set of M linear transforms to the noise-containing digital signal, determining M initial de-noised estimates of each digital element of the digital signal, deriving a combination of weight factors for the M initial de-noised estimates of each digital element by formulating the combination as a linear estimation problem and solving it for the individual weight factors, and formulating a final de-noised estimate of each digital element based on the corresponding M initial de-noised estimates and the combination of weight factors. The combination of weight factors is an optimal combination that is derived such that a conditional mean squared error with respect to the initial de-noised estimates is minimized. The optimal determination is further determined based on a scaling factor that removes explicit dependence to noise variance and on one of several matrices.

摘要： An image recovery algorithm that recovers completely lost blocks in an image/video frame using spatial information surrounding these blocks. One application focuses on lost regions of pixels containing textures, edges and other image features that pose problems for other recovery and error concealment algorithms. The algorithm of this invention is based on the iterative application of a generic de-noising algorithm and does not require any complex preconditioning, segmentation, or edge detection steps. Utilizing locally sparse linear transforms and overcomplete de-noising, good PSNR performance is obtained in the recovery of such regions.

摘要： A color distortion correction is obtained by calculating a color shift of a first color channel with respect to a second color channel along each pixel column of a scanned calibration image. The color shift defines a correction for the color distortions and the correction is then applied to subsequent scanned images. A system for correcting color distortions and an image processing chip configured to determine the color shift are also described.
