IMAGE COMPRESSION BY IMPLEMENTING BACK-PROPAGATION ALGORITHM

WORKING ENVIRONMENT: Operating System :- WINDOWS XP Environment give :- MATLAB 7.0.1 PROJECT INFORMATION: Our project is basically compressing a .bmp image using BackPropagation algorithm in MultiLayered skittish slip away. This is a research topic which we ar trying to utilize in MATLAB 7.0.1. A anxious profits is a trenchant data modeling tool that is able to capture and let complex input/ conkup relationships. The motivation for the development of neural mesh topology technology stemmed from the desire to develop an semisynthetic organization that could perform intelligent tasks similar to those performed by the compassionate brain. Neural networks resemble the human brain in the future(a) two slipway: 1.A neural network acquires friendship through realizeing. 2.A neural networks noesis is stored within inter-nerve cell club strengths known as synaptic weights. The true power and profit of neural networks lies in their major power to represent both elongate and non-linear relationships and in their ability to learn these relationships directly from the data world modeled. Traditional linear models are simply inadequate when it comes to modeling data that contains non-linear characteristics.

Three forms, sensation input layer, one outturn layer and one inexplicable layer. Compression is achieved by pattern the value of K, the number of neurons at the hidden layer, less than that of neurons at both input and output layers. The input image is fracti on up into blocks or vectors of 8*8, 4*4 o! r 16*16 pixels. junction weights connected to each neuron at the hidden layer brush off be delineated by {wji, j = 1, 2, ... K and i = 1, 2, ... N}, which can also be described by a intercellular substance of K*N. From the hidden layer to the output layer, the connections can be represent by {wij : } which is another weight matrix of N*K. Image compression is achieved by training the network in such a way that the coupling...If you want to get a full essay, order it on our website: BestEssayCheap.com
