我们可以提供NLM（Non Local Means）图像去噪算法IP，我们的NLM去噪IP，可以用在FPGA上，也可用在ASIC上。

该NLM IP既可以用在still image,也可用在real-time Video. 有需求的可以联系:sales@wwago-inc.com

we offer the NLM IP to all customers who want to get a clean image , the Customers would be anyone who deals with video or still images.

our NLM IP has already successfully been used by an Israel customer and two USA customers.

关于去噪:

Basic image noise reduction algorithms usually clean the noise in the image by way of low-pass filtering of the image. This method gets rid of noisy pixels, but at this cost of blurring the image – all edges are smeared.

More advanced noise reduction algorithms detect edges in the image, and do low pass filtering along lines perpendicular to the edges – this way the edges are preserved. However, the low-pass filtering is not as effective, because it averages fewer pixels.

NLM is Non-Local-Averaging – it looks at patches of pixels in a relatively large area around the pixel, and makes the low pass with pixels which are located in similar patches.
