Abstract: The present invention relates to a method and system for monitoring and controlling a glass container forming process. The radiation emitted by each hot glass container is measured with measurement unit immediately after the forming machine. The described method normalizes the measurement from glass container to glass container and thereby removes the effects of overall temperature variations between glass containers, changing ambient conditions, and other variations affecting the measurements, which provides a unique quality reference for each glass container. By reviewing this reference for each produced glass container, the quality of the produced containers can be improved.

Abstract: Systems and methods are presented for reconstructing sequences of video frames received from a sending device in a distributed video coding environment. Some of the video frames are received as key video frames fully encoded at the sending device. Others are received as non-key video frames partitioned into pixel blocks. Some of the pixel blocks are indicated for reconstruction via a corresponding previous pixel block of a previous video frame, while other pixel blocks are to be reconstructed by decoding encodings of those pixel blocks received from the sending device. Each received encoding of a pixel block is based on contents of the non-key video frame that contains the pixel block and not on contents of the previous key video frame, nor on contents of any other video frame positioned between the previous key video frame and the non-key video frame in the sequence of video frames.

Abstract: Systems and methods are presented for processing sequences of video frames in a distributed video coding environment. Video frames chosen as key video frames are encoded in their entirety on a sending device, and the encodings are forwarded to a receiving device. Non-key video frames are partitioned into blocks of pixels which are individually processed at the sending device. Some pixel blocks are designated for reconstruction at the receiving device using a similar corresponding pixel block from a previous video frame, and the sending device does not encode those pixel blocks. Other pixel blocks are compressed at the sending device into representations that are sent to the receiving device to facilitate reconstruction of the other pixel blocks at the receiving device. Exceptional efficiency and accuracy may be achieved by employing spatiograms and singular value decompositions in processing pixel blocks of the non-key video frames at the sending device.

Abstract: Motion estimation is efficient to reduce redundant information among successive frames in video compression applications. The blocks in the current frame can be replaced with the neighboring blocks in the spatial directions in the previous frame with small errors. Many types of motion estimation methods such as Block Matching Algorithm are widely used to take a balance between a good image quality and the computation complexity. A Block Matching Algorithm named as New Cellular Search (NCS) Algorithm utilizes two particular search patterns: HCSP and VCSP, in the horizontal and vertical directions to search the best motion vector. Three performance measurements including peak signal to noise ration (PSNR), Average Search Point (ASP), and Mean Square Error (MSE) are used to compare this new search algorithm with some major motion estimations like FS, TSS, CS, and NCDS. The NCS is very efficient in computation reduction while keeping the almost same picture quality.

The region data editor outputs present frame region data, previous compensation region data, and present compensation region data. The video data selector selects one of four video data pieces based on the three pieces of region data and outputs the selected data to the video output unit.

Abstract: A method for forming a video summary for a digital video sequence. The method includes capturing a digital video sequence with a digital video capture device, wherein the digital video sequence includes a plurality of video frames. At least one of the video frames in the digital video sequence is analyzed at the time the digital video sequence is captured to determine one or more feature values. The digital video sequence; is compressed and stored in a processor-accessible memory. The feature values are analyzed, without decompressing the stored compressed digital video sequence, to identify one or more key video snippets, each key video snippet corresponding to a set of video frames from the digital video sequence. The key video snippets are assembled to form a video summary which is stored in a processor-accessible memory.

Abstract: A stereoscopic video viewing limiter extracts factor information related to different factors affecting a viewer of a stereoscopic video display from a video signal, generates corresponding effect coefficients representing the degree of effect on the viewer, integrates the effect coefficients as the viewer watches the stereoscopic video image, compares the integrated values with respective thresholds determined according to the viewer's tolerances for each of the factors, and generates a viewing limitation signal when the tolerances are exceeded. The viewing limitation signal is used to limit viewing to a two-dimensional video image instead of the stereoscopic video image. When several viewers watch the same stereoscopic video display, separate viewing limitation signals are generated, tailored to the viewers' individual stereoscopic viewing tolerances, permitting each viewer to enjoy the stereoscopic video display as long as possible without adverse effects.
