This article studies the methods of computer image acquisition, processing and recognition. The study found that images collected from system often have blurring phenomenon. For this reason, paper proposes a wavelet transform feature extraction algorithm based on colour images, which can separate background without greying image. Through experimental research, it is method efficiently quickly s...

The approach to the differential diagnosis of rheumatic diseases using conventional radiography is systematic and module-oriented, which, with respect to future developments, forms the basis for computer-assisted diagnosis (CAD). The indications follow consensus-based referral criteria and attempts should be made to raise the evidence level of the recommendations. Investigation techniques have ...

One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...

This study explored the autonomy of advanced English as a Foreign Language (EFL) learners in reading comprehension through scaffolding and jigsaw in computer-assisted and conventional contexts. After being homogenized through the reading section of DIALANG proficiency test, a total of 80 female advanced EFL learners with the age range of 21 to 45 were selected as the participants of the study. ...
