Blocking effect reduction of compressed images using classification-based constrained optimization
In this paper we propose an adaptive image restoration algorithm using block-based edge-classi"cation for reducing block artifacts in compressed images. In order to e$ciently reduce block artifacts, edge direction of each block is classi"ed by using model-"tting criterion, and the constrained least-squares (CLS) "lter with corresponding direction is used for restoring the block. The proposed re...
متن کاملEnhancement of Noise Performance in Digital Receivers by Over Sampling the Received Signal
In wireless channel the noise has a zero mean. This channel property can be used in the enhancement of the noise performance in the digital receivers by oversampling the received signal and calculating the decision variable based on the time average of more than one sample of the received signal. The averaging process will reduce the effect of the noise in the decision variable that will approa...
متن کاملA high performance FIR filter dedicated to digital video transmission
| A digital lter is one of the fundamental elements in the digital video transmission, and a multiplier acts as the key factor that determines the operation speed and silicon area of the lter. Even though the coe cients to the lter are desired to be programmable, it is possible to change coe cients in the vertical y-back interval of television receivers. This allows the preloadability of coe ci...
متن کاملVirtual TV Channel: Filtering, Merging and Presenting Internet Broadcasting Channels
Broadcast-based information dissemination systems on the Internet are becoming increasingly popular due to advances in the area of Web technology and information delivery. In this paper, we propose a concept and a way to construct a virtual TV channel, which is a user-deened (virtual) channel from existing push-based Internet channels. Our virtual TV channel is (1) to lter contents of multiple ...
متن کاملDigital filter analysis toolbox for MATLAB
A matlab toolbox has been developed that analyzes digital lter structures. After describing the digital lter structure in a SPICE-like format, the programs of this toolbox can map a digital lter structure into a state-space description, convert a state-space description to a z-domain transfer function, compute the maximum signal magnitude when input is bounded by unity, compute noise power at t...
