20120287237 | METHOD AND APPARATUS FOR PROCESSING VIDEO SIGNALS, RELATED COMPUTER PROGRAM PRODUCT, AND ENCODED SIGNAL - An embodiment of a method is disclosed for encoding a digital video signal including a first video sequence and a second video sequence jointly forming a stereo-view digital video signal. The method includes: subjecting the first video sequence to discrete cosine transform, quantization and run-length coding to produce a sequence of blocks of non-zero digital levels representative of the first video sequence, subjecting the second video sequence to discrete cosine transform, quantization, run-length coding and variable length coding to produce digital messages representative of the second video sequence, merging the bits of the digital messages into the sequence of blocks of digital levels by substituting the bits of the digital messages for respective Least Significant Bits of e.g. the last digital level in the blocks representative of the first video sequence to produce an encoded digital video signal representative of the first video sequence and the second video sequence. | 11-15-2012 |
20140161359 | METHOD FOR DETECTING A STRAIGHT LINE IN A DIGITAL IMAGE - An embodiment is a computer-implemented method for detecting a straight line in a digital image comprising a plurality of pixels comprising the steps: detecting an edge in the digital image, generating a first straight line which passes through a first pixel of the detected edge, generating a second straight line which passes through a second pixel of the detected edge, which is different from the first pixel, determining at least two intersections with a boundary of the digital image for each generated straight line, determining a set of two parameter values for each generated straight line based on the respective determined at least two intersections, wherein the set of two parameter values uniquely determines the respective generated straight line, and detecting the straight line in the digital image based on the determined sets of two parameter values. | 06-12-2014 |
