MATLAB code: using Laplacian mask enhance for image "ngc6543.jpg".

MATLAB code:
using Laplacian mask enhance for image "ngc6543.jpg".

Expert Solution

This will be done by locallapfilt which will approximate the algorithm by discretizing the intensity range into a number of samples defined by the 'NumIntensityLevels' parameter. This parameter is used to balance speed and quality. The parameter is set to 100 here.

A = imread('ngc6543.jpg');

imshow(A)

%Using a sigma value to process the details and an alpha value to increase the contrast, effectively enhancing the local contrast of the image.

sigma = 0.2;
alpha = 0.3;

%The value of sigma and alpha can be adjusted to apply various filters on the image

B = locallapfilt(A, sigma, alpha, 'NumIntensityLevels', 100);

imshow(B)

Applying the above enhancements to the image:

Using Matlab 1. Create a color image of size 200 × 200. The image should have a blue background. 2. Create 100 yellow regions within the image that have a variable size. More specifically, their width should be an odd number and vary between 3 and 7 and their height should also be an odd number and vary between 3 and 7. For example, you may get rectangular regions of size 3 × 3, 3 × 5, 5 × 3,...

I want to create an image compression program with matlab use PCA. I have the code listed below. But this code is fail, the image is colorless, but still gray. Can you help me to fix my code. clc clear all picture = im2double(imread('picture1.jpg')); Red = picture(:,:,1); premean = mean(Red(:)); premax = max(Red(:)); premin = min(Red(:)); x = size(Red,1); y = size(Red,2); Z = ones(x,y)*premean; A = (Red - Z)*(1/premax - premin); B = cov(A); [veceig,eig,C] = pcacov(B); NewRed =...

(1)Using the Matlab code developed in Software Assignment #1: a. Convert the code that generates the random number (H,T) with equal probabilities into a function called myBernolli(p, S) that takes as an input the probability of success p and S is the outcome defined as success (either T or H) and returns the outcome of the trial (either T or H). b. Test that your function is actually producing the successful outcome with probability p by running the function in...
