A combined cycle fatigue (CCF) testing system with ultrasonic frequency component was developed toevaluate the CCF properties of S350 steel welded joints in this
A direction-based adaptive switching(DBAS) filter is presented for the removal of high-density impulse noise in images. The extrema detection and 28-directional detection are employed to discriminate
An efficient adaptive approximation demosaicking algorithm based on the sampled edge pattern was presented for mosaic images from Bayer color filter array. The proposed algorithm determined edge patte
