Abstract: A system and method that will improve QoS (Quality of Service) of wireless video transmission systems. This is done by “in-fly” monitoring of BER by periodically transmitting “test images”, which images are known to the RF-receiver (Rx). BER can be automatically computed, within a related BIT (Built-in-Test) procedure that is also the subject of this invention. This allows predictions of a proper increasing, or decreasing of bandwidth OVH-level, in order to compensate for a BER-change. BER computation is facilitated by distinguishing video frames based on whether they depict new spatial events or related temporal events. Another subject of this invention is a motion-based pre-ATR method that is an introduction to common ATR, or pattern recognition methods. Yet another subject of this invention is a process of implanting error correcting bits into a payload, in the form of imperceptible watermarks.

Abstract: An eye region is extracted from an input image. A poor pupil hue quality region is extracted from the eye region. A high brightness region is extracted from the poor pupil hue quality region. A region obtained by excluding the high brightness region from the poor pupil hue quality region is extracted as a red-eye region. The high brightness region is corrected by using a method different from that for the red-eye region.

The image is separated into N vertical bands each comprising a plurality of lines and at least one column of macro-blocks if the macro-block is processed sequentially line by line, or into N horizontal bands each comprising a plurality of columns and at least one line of macro-blocks if the macro-block is processed sequentially column by column. One of the N bands is processed by each processor, and the processing operations performed by the N processors is synchronized.

Abstract: The present invention provides a technology that is implemented in a motion compensation image coding device or a coding method and intended to code motion picture data in real time by performing a decreased number of arithmetic operations so as to determine a motion vector. In motion compensation image coding, macroblocks and sub-blocks into which each of the macroblocks is divided are searched for a motion vector with integer pixel precision. Based on the results of the search, a shape of a block that should be searched for a motion vector with decimal pixel precision is determined as a shape mode. The block of the shape mode is searched for a motion vector with decimal pixel precision, whereby a motion vector needed to produce predictive image data is determined.

Abstract: A system and method for determining a predicted window level transformation for image data associated with a loading image based on user selections of window level transformations. A learning image associated with a set of learning context characteristics is displayed to the user in order to elicit selection of a first selected window transformation. Learned rules are established based on the learning context characteristics and the first selected window transformation. When there is a request to display a loading image associated with a set of loading context characteristics, the learned rules are evaluated based on the loading context characteristics to determine a set of inferred window level transformations. The predicted window level transformation is then determined by selecting the most desirable inferred window level transformation.

Abstract: Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.

Abstract: A position code is recorded by capturing a sequence of images while writing on the base with a user unit. The position code may be decoded to a sequence of absolute positions reflecting the movement of the user unit over the base. If the position code in any image is not sufficiently recorded, e.g. because it is obscured by other graphics on the base, the spatial relationship of the image to another image in the sequence is determined. If the position code in this other image in the image sequence is decodable to an absolute position, the absolute position of the image in which the position code is not decodable could nevertheless be determined by using the spatial relationship. In this way the movement of the user unit can be recorded even though the position code is obscured, which could be the case when the same printing ink is used for both the position code and other graphics on the base.

Abstract: A display driving apparatus and method using a display device, such as a liquid crystal display device, and a medium for implementing a method of display driving method are provided. The display driving apparatus includes: an encoding unit which compresses and encodes image data to be displayed by the display device; a memory which stores the encoded image data; a memory control unit which stores the encoded image data in the memory and reads the encoded image data from the memory; and a decoding unit which decodes the encoded image data read out from the memory to restore the image data. Input image data is compressed and encoded in units of blocks, and the encoded image data is stored in a memory. Thereafter, the encoded image data stored in the memory is decoded, and the decoded result is output to a display device. Thus, it is possible to reduce the size of a memory included in a display driving apparatus without deteriorating the quality of an image displayed.

Abstract: Systems and methods for image pattern recognition comprise digital image capture and encoding using vector quantization (“VQ”) of the image. A vocabulary of vectors is built by segmenting images into kernels and creating vectors corresponding to each kernel. Images are encoded by creating a vector index file having indices that point to the vectors stored in the vocabulary. The vector index file can be used to reconstruct an image by looking up vectors stored in the vocabulary. Pattern recognition of candidate regions of images can be accomplished by correlating image vectors to a pre-trained vocabulary of vector sets comprising vectors that correlate with particular image characteristics.
