Nov 05, 2010 · how to generate gaussian noise and gaussian filter in matlab? Hi, I am a newbie in matlab and dsp. I have a signal and would like to generate gaussian noise and use a gaussian filter to remove the noise. From what i have gathered from matlab, to generate gaussian noise i would use randn(1,256) to generate gaussian noise and add it to my signal.
Functional near-infrared spectroscopy (fNIRS), a promising noninvasive imaging technique, has recently become an increasingly popular tool in resting-state brain functional connectivity (FC) studies. However, the corresponding software packages for FC analysis are still lacking. To facilitate fNIRS-based human functional connectome studies, we developed a MATLAB software package called &#x201C ...

On the other hand, the region seeds r are already in row major format, which is the standard MATLAB format for pixel indices. Instead of transposing the frames, one can start by transposing the image. In this case, the frames f have the standard image convention, but the region seeds are in column-major format and may need to be "transposed" as in:

Aug 31, 2013 · In signal processing, noise is typically the unwanted aspect. In a noisy room it’s harder to hear someone than in a quiet room. Audio noise is random numbers arranged in a line (1D). In a noisy image it’s harder to see a pattern than in a clean image. Image noise is random numbers arranged in a grid (2D). You can also have noise in 3D, 4D, etc.
