چکیده

Progressive transmission of images based on lapped orthogonal transform (LOT), adaptive classification and human visual sensitivity (HVS) weighting is proposed. HVS weighting for LOT is developed using a general technique that can be applied to any orthogonal transform. The method is compared with discrete cosine transform (DCT) based progressive image transmission (PIT). It is shown that LOT based P IT yields subjectively improved images compared to those based on DCT.

Lapped-orthogonal-transform-based adaptive image watermarking

A robust, invisible watermarking scheme is proposed for digital images, where the watermark is embedded using the blockbased lapped orthogonal transform (LOT). The embedding process follows a spread spectrum watermarking approach. In contrast to the use of transforms such as discrete cosine transform, our LOT watermarking scheme allows larger watermark embedding energy while maintaining the sam...

The Orientation Adaptive Lapped Orthogonal Transform for Image Coding

In this paper, a lapped orthogonal transform adapted for local directionality of an image is proposed and its application in adaptive image coding is presented. First, we address the problem to construct the lapped orthogonal transform with short and long functions such that the long functions are twice the length of the short functions, and derive the transform with the optimal short functions...

Lapped Orthogonal Transform Designed for Error Resilient Image Coding

This paper describes a new design method for lapped orthogonal transforms (LOTs) that can provide a desired tradeoff between coding efficiency and resilience to transmission errors. Traditionally, LOT bases have been designed to maximize the coding efficiency solely. When certain coefficients are lost due to impairments in the transmission channel, the reconstructed image is often unsatisfactor...

Image Compression Algorithms under JPEG with Lapped Orthogonal Transform and Discrete Cosine Transformation

This Paper Focus On Image Compression.It is used specially for the compression of images where tolerable degradation is required. With the wide use of computers and consequently need for large scale storage and transmission of data, efficient ways of storing of data have become necessary. Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the i...
