Tetrolet Transform, a wavelet based efficient and effective transform, utilizes supports formed by connecting four identical squares known as tetrominoes such that each is connected to at least one other square along its boundary. Haar wavelets are defined on these tetrominoes so as to form an localized orthonormal basis. The procedure is applied on small 4×4 partitions of the low pass image and the...
Easy Path Wavelet Transform (EPWT), a wavelet based compression technique that averages in adaptive neighborhoods of image intensity points, is utilized for the sparse representation of two-dimensional data. EPWT, when applied upon images, operates along the permutations of original image indices exploiting the local correlations in an uncomplicated manner. The highly correlated array of function...
