Hi, i am trying to add color noise to an image but i dont know if there is a function in matlab to generate a color noise, because imnoise just add gaussian, salt & pepper and others. I hope you could help me. Thank you 댓글 수: 3 이전 댓글 1개 표시 claudia...

addnoise函数添加椒盐噪声可用于图像质量测试。泊松噪声也能利用addnoise函数添加到信号中。利用该函数可研究噪声对信号特征的影响。在信号处理实验中addnoise函数常被使用。addnoise函数添加噪声后信号频谱会发生变化。其有助于分析算法在含噪信号下的性能。可通过调整参数让addnoise函数添加有色噪声。 图像去噪算法测试常...

Add Gaussian noise to the image. J = imnoise(I,'gaussian',0,0.025); Display the noisy image. Because the image is quite large, display only a portion of the image. imshow(J(600:1000,1:600)); title('Portion of the Image with Added Gaussian Noise'); ...
