Modulated by global-, continental-, regional-, and local-scale processes, convective precipitation in coastal tropical regions is paramount in maintaining the ecological balance and socioeconomic health within them. The western coast of the Caribbean

The Iterated Block Matching is a Fractal method of near real time Compression of images. It was introduced by Jacquin in 1992. This method encodes an image using the image itself. In this paper, the mathematical procedure of this method, for both enc

Mandelbrot [1] in his observation of the “The Fractal Geometry of Nature” has laid out a new scientific thought that what we see around us is an intricate arrangement of features. This lead to the discovery of the Fractal Geometry or just Fractal

The conventional iterated block matching fractal encoder/decoder is computationally intensive. The decoder converges slowly after many iterations. In this work, the encoder is improved leading to a higher compression ratio, and the image convergence

Changes in vegetation can affect our health, the environment and the economy. Understanding this, twenty years ago scientists began to use satellite remote sensors to monitor major fluctuations in vegetation and understand how it affects the environm
