Still Image and Video Compression with MATLAB

This booklet describes the foundations of photograph and video compression ideas and introduces present and well known compression criteria, akin to the MPEG sequence. Derivations of suitable compression algorithms are constructed in an easy-to-follow model. a number of examples are supplied in each one bankruptcy to demonstrate the strategies.

From Elementary Probability to Stochastic Differential Equations with MAPLE

This is often an advent to probabilistic and statistical recommendations essential to comprehend the elemental principles and techniques of stochastic differential equations. according to degree concept, that is brought as easily as attainable, it presents sensible talents within the use of MAPLE within the context of likelihood and its functions.

Example text

This process is said to one complete iteration. Next randomly selected value is selected and the above described process is repeated for 100 iterations. The order in which the values are selected in the first 6 iterations is not moving towards the local minima point which can be noted from the figure 1-6. This is due to the fact that the initial simulated temperature of the annealing process is high. 1. Artificial Intelligence 21 Figure1-7 Illustration of Simulated Annealing 1 As iteration increases the simulated temperature is decreased and the value selected for the variable ‘x is moving towards the global minima point as shown in the figure 1-7.

E = h1 * (1-h1)* [(t1-o1) + (t2-o2)] Step 5: Adjustment of Bias bh (n+1)= bh (n) +e* γH b1 (n+1) = b1 (n) + (t1-o1)* γO b2 (n+1) = b2 (n) + (t2-o2)* γO Step 6: Repeat step 3 to step 5 for all the pairs of input vector and the corresponding desired target vector one by one. Step 7: Let d1, d 2 d3 …d n be the set of desired vectors and y1, y2 y3 yn be the corresponding output vectors computed using the latest updated weights and bias vectors. The sum squared error is calculated as SSE= (d1- y1)2 + (d2- y2)2 +(d3- y3)2 +(d4- y4)2 + … (dn- yn)2 Step 8: Repeat the steps 3 to 7 until the particular SSE is reached.

The membership value associated with the elements of the set AUB is the minimum of the corresponding membership values collected from the set A and B. 2 Fuzzy Logic Systems Let us consider the problem of obtaining the optimum value of the variable ‘Z’ obtained as the output of the fuzzy logic system decided by the values of the variable ‘X’ and ‘Y’ taken as the input to the fuzzy logic system using fuzzy logic algorithm. The values of the variable ‘X’ vary from Xmin to Xmax Actual value of the variable is called crisp value.
