Generate a Gaussian Image without adding noise
<p>I want to generate a Gaussian Image by Matlab. It has 3 circles (as three classes). The intensity in each circle will be followed by Gaussian distribution. Thus, the histogram of the image will be multiplicate Gaussian distribution as a <a href="https://stackoverflow.com/questions/35725040/how-to-generate-a-multiplicate-2d-gaussian-image-distribution-in-matlab">question</a>. However, I used a free-noise image and added it with Gaussian noise to make the multiplicate Gaussian distribution, it is very noise. In this question, I am looking for a way to generate synthetic Gaussian image, which different with my previous method (adding noise). Thank for reading </p>
