Experiments with wavelet and other edge detection techniques
R. Rifaat, Witold Kinsner · 2002
This paper discusses experimental work with a wavelet edge detection technique for still images. A brief overview of wavelets and other methods for edge detection is given along with images comparing the results. Several different image classes are examined and processed. Two test images are discussed in order to determine the properties of the system. An experimental image is used to obtain insight into the practical application of the technique. Advantages of the wavelet transform method include multiscale resolution, improved noise handling, and edge direction information.
