The methods of image edge detection based on the differential, wavelet transform and image morphology are introduced in the paper. Differential operator edge detection method is based on the edge of the adjacent regions' boundary that is not continuous with the gray, using derivative to detect the edge, Wavelet transform edge detection is by means of selecting the appropriate wavelet function to make...
According to the symmetric characteristics of bispectrum, a novel feature extraction scheme, which includes the summation-at-every-column feature vector, the summation-at-every-row feature vector and their combination in a triangle area, one of the 12 symmetric areas of bispectrum, is proposed. By using One-against-One (OAO) method of multi classification of Support Vector Machine (SVM), the mean...
The rapid development of Web 2.0 bring the flourish of web reviews. Web reviews are usually released in form of structured records. As the important information source for many popular applications(e.g. monitoring and analysis of public opinion), review records need to be extracted accurately from web pages. To the best of our knowledge, little work in literatures has systemically investigated this...
