Training Using Simulated Annealing Algorithm (Input: Quantized Image and Filter Matrix)

Goal: To Select Best Edge Filters

Initialize the Population Size N and Number of Generations

While (number of generations is not reached)

Objective Function Evaluation

If Objective Function Decreases

Update the Best Solution for Each Filter Vector

Reduce the Current Temperature

Generate a New Trial Solution and Go to Evaluation Step

Else If Metropolis Criterion Is Meet

Go to Update Step

Else

Go to Reduce Temperature Step

End While

Apply Best Selected Edge Filter

End of SA

Output: Evolutionary Edge Detected Image

Training Using Particle Swarm Optimization + SA (Input: Edge Detected Input Image)

Goal: To Segment the Input Image

Initialize the Population Size N and Number of Generations

While (number of generations is not reached)

Initialized Particles with Random Position and Velocity for PSO

Evaluate the Fitness of Particles for each Pixel and Their Corresponding Distance for PSO

Objective Function Evaluation for SA as Optimizer

Find and update pbest and gbest for PSO

Reduce The Current Temperature for SA

Calculate and Update Velocity and Position for PSO

Generate a New Trial Solution and Go to Evaluation Step for SA

Show gbest the Optimal Solution for PSO

Desirable Temperature Reached for SA

Update the Best Solution Found for Pixel and Distance by PSO+SA

End While

Apply Best Clusters Found on Image to Segment

End of PSOSA

Overlay All Evolutionary Techniques

Output: Evolutionary Segmented Image

function Culture = AdjustCulture(Culture, spop)

n = numel(spop);

nVar = numel(spop(1).Position);

for i = 1:n

if spop(i).Cost<Culture.Situational.Cost

end

for j = 1:nVar

if spop(i).Position(j)<Culture.Normative.Min(j) ...

|| spop(i).Cost<Culture.Normative.L(j)

Culture.Normative.Min(j) = spop(i).Position(j);

Culture.Normative.L(j) = spop(i).Cost;

end

if spop(i).Position(j)>Culture.Normative.Max(j) ...

|| spop(i).Cost<Culture.Normative.U(j)

Culture.Normative.Max(j) = spop(i).Position(j);

Culture.Normative.U(j) = spop(i).Cost;

end

end
