For noise reduction, the decomposed images are filtered using a bilateral filter and soft-thresholding. And then, the dynamic ranges of the filtered subbands are enhanced by considering local contrast using the modified luminance compression function. Finally, the color of the tone-mapped image is ...
PURPOSE: An adaptive noise reduction filter is provided to effectively remove noise in response to luminance change without additional line memory. CONSTITUTION: An adaptive noise reduction filter includes a multiplying and adding portion(231) multiplying first, second and third vertical luminance signals...
The reduction of Gaussian noise is still an important task in video systems. For this purpose a spatio-temporal noise reduction scheme for interlaced video is presented. It consists mainly of a subband based temporal recursive filter which makes use of some special properties of the human visual ...
