create a gabor with image, theta, lambda, psi, gamma, sigma in matlab

To create a Gabor filter in MATLAB, you can use the function gabor from the Image Processing Toolbox. The function takes six arguments:

1. image: The image you want to filter
2. theta: The orientation of the filter (in radians)
3. lambda: The wavelength of the sinusoidal factor of the filter
4. psi: The phase offset of the filter
5. gamma: The spatial aspect ratio
6. sigma: The standard deviation of the Gaussian envelope

Here's an example of how to create a Gabor filter with the parameters specified above and apply it to an image:

main.m
% Load an example image
img = imread('cameraman.tif');

% Define the Gabor filter parameters
theta = pi/4;
lambda = 20;
psi = 0;
gamma = 0.5;
sigma = 5;

% Create the Gabor filter
gb = gabor(lambda, theta, sigma, psi, gamma);

% Apply the filter to the image
output = imfilter(img, gb);

The output variable will contain the filtered image. You can adjust the parameters of the filter to achieve different results.
