摘要： A motion compensation method for estimating motion between one image frame and another image frame. Each frame is divided into a number of block, and a match is found for a block of one frame within a search area in another frame. A motion vector is determined that represents the geometrical displacement between the two matched blocks, by determining whether motion estimation is being performed near pattern-like objects in the frames. A new frame is reconstructed by interpolation as a function of the two existing frames based on the motion vector and a degree of being a pattern-like object in a frame.

摘要： An example-based method and system for electronic display color calibration is provided. By comparing the colors of commonly available objects with a color database under a controlled lighting condition, the user adjusts the gain and offset parameters of the Red, Green and Blue color components of the display. Two different methods are provided, wherein one method involves manipulating the comparison colors in the RGB color space, and the other method involves manipulating the comparison colors in the CIE x-y plane. Two different systems that incorporate the example-based color calibration methods are also provided, wherein one system directly implements the calibration method in the television system, while the other system implements the calibration method as a separate tool for viewers to calibrate the color of their displays.

摘要： A method and corresponding systems for using remote control to realize standard colors on displays. Two examples of remote controls are provided, one with color sensors and the other with white LEDs. For each example a calibration pattern is displayed which allows a user to calibrate the display color conveniently. For using the remote control with color sensors, an algorithm for the display to adjust the input RGB color, based on the color measurements from the remote control is provided. This allows the display output RGB color so that the display shows the same color as the input RGB signal is sent to standard color display.

摘要： A superior Color Transient Improvement technique is adaptive to the local image features, so that more natural color edge transition improvement can be accomplished. A gain control function is provided that depends on the local image feature so that different regions of the image can be treated differently. Further, a correction signal is controlled in such a way (by the local image feature) that neither undershoot nor overshoot occurs, eliminating the need for post-processing for undershoot/overshoot removal.

摘要： A rank-determining device determines the rank of a particular sample value from a set of digital sample values by utilizing two different thresholders that are implemented by comparators. The rank of the sample value is decomposed by thresholding the sample value with all of the sample values in the set of digital sample values, and in this manner eliminates the necessity of a sorting operation. This decomposition of the rank will is referred to as self-threshold decomposition. A plurality of these rank-determining devices can be combined to form a rank determining apparatus in order to find the rank of each one of the digital samples in the set of digital samples. Because the rank-determining apparatus implements self-threshold decomposition, rank- and order-statistic based filters, such as the median filter, can be realized in a feasible manner.
摘要翻译：等级确定装置通过利用由比较器实现的两个不同的阈值来确定来自一组数字样本值的特定采样值的等级。样本值的等级通过将数据样本值集合中的所有样本值阈值化为样本值来分解，从而消除了排序操作的必要性。等级的这种分解将被称为自阈值分解。可以将多个这些等级确定装置组合以形成等级确定装置，以便找到该组数字样本中的每一个数字样本的等级。由于等级判定装置实现自阈值分解，所以基于秩和统计的滤波器，如中值滤波器，可以以可行的方式实现。

摘要： An improved noise reduction process by wavelet thresholding utilizes a discrete wavelet transform to decompose the image into different resolution levels. A thresholding function is then applied in different resolution levels with different threshold values to eliminate insignificant wavelet coefficients which mainly correspond to the noise in the original image. Finally, an inverse discrete wavelet transform is applied to generate the noise-reduced video image. The threshold values are based on the relationships between the noise standard deviations of different decomposition levels in the wavelet domain and the noise standard deviation of the original image.

摘要： A line thinning algorithm (LTA) for a grayscale input image, wherein the LTA is a separable algorithm that performs on each row of input grayscale image sequentially from top to bottom and subsequently on each column from left to right, independently. The LTA is very robust to the noise and is capable of thinning lines even in noisy image areas. The level of thinning is fully adaptive to the transition range and dynamic range locally in each line segment. Furthermore, the LTA for a black line can be easily generalized for a white line counterpart by simply switching the sign of one parameter DELTA from positive to negative without changing other aspects of the LTA.

摘要： A video scaling process system, wherein the high frequency components of the input video sequence are compensated for, prior to video scaling. The video scaling system includes a pre-compensator for compensation of the high frequency components of the input video sequence, and a video scaler. The pre-compensator includes a high frequency component extractor, a noise detector and a shoot suppressor. The high frequency component extractor extracts the high frequency compensation component from an input video sequence. The noise detector adjusts the gain of the compensation to avoid the enhancement of the noise component. The shoot suppressor further adjusts the gain of the compensation to avoid shoot artifacts. The adjusted high frequency compensated video is added back to the input video. The pre-compensated video sequence is then passed through a video scaler to obtain the scaled video. As such, the sharpness of the scaled video is maintained or even enhanced.

摘要： A method is provided for enhancing the details of an image while suppressing or preventing shoots that would otherwise occur during a prior art enhancement process. The enhancing method is based on recognizing that Shoots are likely to occur at edges of an image to be enhanced, and therefore, if the enhancement is sufficiently reduced or even possibly eliminated at the edges of the image, the Shoots that would otherwise occur will be suppressed or even possibly eliminated. A gain suppressing function is used to attenuate the enhancement at the edges of the image. Preferably, the gain suppressing function inherently identifies the edges of the image to be enhanced.

摘要： A ringing area detector classifies the input image into two regions: a mosquito noise region (i.e. filtering region) and a non-mosquito noise region (i.e. non-filtering region), and uses this classification information to adaptively remove the mosquito noise in a mosquito noise reduction system. The mosquito noise reduction system includes a ringing area detector, a local noise power estimator, a smoothing filter, and a mixer. The ringing area detector includes an edge detector, a near edge detector, a texture detector, and a filtering region decision block. The ringing detection block detects the ringing area where the smoothing filter is to be applied. The local noise power estimator controls the filter strength of the smoothing filter. The smoothing filter smoothes the input image. The mixer mixes the smoothed image and the original image properly based on the region information from the ringing area detection block.
