X-ray flaw detection is widely used in non-destructive area. The intuitive defect information can be obtained through the film, which usually digitized into high greyscale image by a 12-bit or 16-bit, called super 8-bit, industrial scanner. When an ordinary 8-bit monitor displays image, it appears loss of detail information, blurring and other problems. Therefore, this paper, pseudo-colour enha...

Reversible logic has attracted substantial interest due to its low power consumption which is the main concern of low power VLSI circuit design. In this paper, a novel 4x4 reversible gate called inventive gate has been introduced and using this gate 1-bit, 2-bit, 8-bit, 32-bit and n-bit group-based reversible comparator have been constructed with low value of reversible parameters. The MOS tran...

In this paper, we propose a bit-allocation algorithm to transmit textured 3D models over low bit-rate channels. Both the geometry and the texture are progressively and independently compressed. Distribution of the bit budget between mesh and texture is based on a novel distortion measure, which quantifies the perceptual difference resulting from simplifying the geometry or using a low-resolutio...

introduction automated methods for sperm characterization in microscopic videos have some limitations such as: low contrast of the video frames and possibility of neighboring sperms to touch each other. in this paper a new method is introduced for detection of sperms in microscopic videos. materials and methods in this work, first microscopic videos are captured from specimens of human semen. s...

Advances in sub-micron technologies make low power consumption and delay a major concern for present day systems. These parameters play critical role the performance of most widely used wide fan-in-dynamic logic gates. fan-in dynamic gatesare employed designing high speed tag comparators which are blocks cache memory. The Stack-Scheme Clocked-Bleeder Domino (SS-CBD)tries to have an insight on 4...
