Based on the study of motion vector distribution from several commonly used test image sequences, a new diamond search (DS) algorithm for fast block-matching motion estimation (BMME) is proposed in this paper. Simulation results demonstrate that the proposed DS algorithm greatly outperforms the well-known three-step search (TSS) algorithm. Compared with the(More)
The paper presents an extension of content based image retrieval (CBIR) techniques based on Overlap Modified Block Truncation Coding (BTC) and Overlap Gabor Magnitude. Modified Block truncation coding based features is one of the CBIR methods proposed using color features of image. The approach basically considers red, green and blue planes of an image to
Berberine is a plant-derived compound used in traditional Chinese medicine, which has been shown to inhibit cell proliferation and migration in breast cancer. On the other hand, vasodilator-stimulated phosphoprotein (VASP) promotes actin filament elongation and cell migration. We previously showed that VASP is overexpressed in high-motility breast cancer(More)
For the management of IP (Internet Protocol) networks, flow counting is significant because of various applications such as denial-of-service (DoS) attack detection, etc. Although several flow counting algorithms have been proposed in literature, they have disadvantages in computational time and accuracy. This paper proposes a flow counting algorithm that(More)
Making full uses of the processing performance and peripheral features of DSP TMS320DM6437 chip, we innovatively designed a vehicle collision avoidance system with low-cost, high reliability. The system can achieve functions of vehicle detection, vehicle distance measurement and auto-assisted control. Through simulations and experiments, we verified the(More)
Atomic layer deposition (ALD) technology is introduced to fabricate a high sensitivity refractometer based on an adiabatic tapered optical fiber. Different thicknesses of titanium dioxide (TiO₂) nanofilm were coated around the tapered fiber precisely and uniformly under different deposition cycles. Attributed to the higher refractive index of the TiO₂(More)
