Multi-carrier PAP reduction method using sub-optimal PTS with threshold
Oh-Ju Kwon,Yeong-Ho Ha +1 more
TL;DR: An orthogonal frequency division multiplexing (OFDM) system, which through the use of sub-optimal PTS combined with a preset threshold, achieves low computational complexity to find optimum weighting factors.
Journal ArticleDOI
Spatial color descriptor for image retrieval and video segmentation
TL;DR: Experimental results show that the proposed color descriptor could produce a high image retrieval rate and accurately detect abrupt scene-cuts in a video analysis and the storage space required for the image histogram values can be effectively reduced.
Journal ArticleDOI
Adaptive scan rate up-conversion system based on human visual characteristics
TL;DR: This new system was mainly developed for doubling the scan rate in an NTSC system; however, it can be used in the format conversion in an HDTV system and the VLSI architecture is very simple.
Journal ArticleDOI
Stereo matching using genetic algorithm with adaptive chromosomes
TL;DR: A new stereo matching scheme using a genetic algorithm is presented to improve the depth reconstruction method of stereo vision systems and considers the matching environment as an optimization problem and finds the optimal solution by using an evolutionary strategy.
Journal ArticleDOI
Stereo correspondence using the Hopfield neural network of a new energy function
TL;DR: An approach using a Hopfield neural network to the stereo correspondence problem for extracting the 3D structure of a scene by transforming constraints into an energy function, whose minimum value corresponds to the best solution of the problem, on the Hopfield network.
