A perceptual image coder for the compression of monochrome images is presented here, in which the coding structure is coupled with a vision model to produce coded images with an improved visual quality at low bit-rates. The coder is an improvement on the Joint Photographic Experts Group (JPEG -Discrete Cosine Transform (DCT) based) image compression(More)
In this paper, a new denoising technique for images corrupted with additive white Gaussian noise is presented. The technique used here is to combine the wavelet transform and the curvelet transform with anisotropic diffusion. Curvelet transform is a new geometric-based multiscale transform developed to give sparse representation of images with singularities(More)
A data driven background subtraction algorithm where each background pixel is modeled with a representative set of samples is presented. The samples are pixel values observed in preceding frames. Each pixel in an incoming frame is classified as background or foreground by comparing the pixel value with the samples in pixel's background model. The background(More)
A perceptual image coder for the compression of monochrome images is presented here, in which the coding structure is coupled with a vision model to produce coded images with an improved visual quality at low bit-rates. The coder is an improvement on the current image compression standard, JPEG2000. The proposed coding structure incorporates the human(More)
High Efficiency Video Coding (HEVC) is a new standard under development by the ISO and ITU-T. In this work an encoder which incorporates HVS models into the basic coding structure of the recommended HEVC standard is implemented, to improve the quality of the standard coder. Since human eye ultimately decides the quality of the received signal and the sole(More)
Vehicle detection and classification is the most important and challenging stage of traffic surveillance using computer vision techniques. The videos captured using the closed circuit television (CCTV) cameras placed in roadsides or driveways are used for the surveillance. The surveillance system includes detection of moving vehicles, counting the number of(More)
