In the existing methods of binarization, most edge information is lost and the resulted binary image gets blurred. Edges carry most of the information in an image. Here, some techniques for the preservation of edge information in images are proposed and studied. Techniques are based on the filtering operation by some newly developed edge preserving filters followed by thresholding operation. The resulted...
A real-time digital filter can perform filtering operation on real-time signals. This paper presents the implementation and performance analysis of real-time FIR (finite impulse response) digital filter on audio signals. Digital filters (low pass, high pass and band pass) implemented using DSP block sets are used to remove the higher and lower frequency components of real-time voice signals. This...
