Continuing with article series about the denoise filters, we had seen that the Gauss filter had a very high sensitivity to noise due to it's static nature. Now is time to analyze a dynamic denoise filter based in the arithmetic mean of the input pixels, this is called the Mean Denoise Filter. This filter adapts it's convolution kernel according to the values of the input pixels.

Denoise filters: Gauss
We have seen before about convolution filters, and at the end of that article we have seen a kernel used for removing noise in an image, that is random spurious pixels in a image, the process of removing that random pixels is called Denoise. In this case I will show you the general form of the denoising kernel based in gaussian distribution.

Integral image and image blur
In this post I will show you an image processing technique that provides a great boost to algorithms that requires the summation of a large number of pixels, this technique is called integral image, also known as Summed Area Table (SAT). Additionally, I will show you an algorithm used to blur an image that take advantage of the integral image.

Image convolution
In this post I want explain a one of the most common and simple algorithm used in image processing. I will give a very basic introduction to its mathematical formulation, the source code in C++/Qt, and a some output examples.

Webcamoid 6.1.0 ready, what next?
5 months passed after the last release, in this post I want to explain why Webcamoid's development is going such slow, and what features I are planned for the next releases.
Download Webcamoid 6.1.0
