According to the traditional immunization procedure, after the first injection of the sample A (emulsion of aimed antigen and Freund's complete adjuvant) to immunize rabbit, successive injections of the sample B (emulsion of aimed antigen and Freund's incomplete adjuvant) were followed every 2-4 weeks. In general, high titer of the corresponding polyclonal(More)
Laparoscopic orchidopexy (LO) has been widespread used in the management of non-palpable testis (NPT) in children. However, the real advantages of LO over traditional open orchidopexy (OO) still remain exclusive. Published studies until August 31, 2010 were searched from Medline, Embase, Ovid, Web of Science, and Cochrane databases. Randomized controlled(More)
Immune evasion of cancer cells is mainly due to the impaired transduction of apoptotic signals from immune cells to cancer cells, as well as inhibition of subsequent apoptosis signal cascades within the cancer cells. Over the past few decades, the research has focused more on the impaired transduction of the apoptotic signal from immune cells to cancer(More)
A fast and robust video segmentation technique is proposed to generate a coding optimized binary object mask in this work. The algorithm exploits the color information in the Luv space, and combines it with the motion information to separate moving objects from the background. A non-parametric gradient-based iterative color clustering algorithm, called the(More)
Video object segmentation is an important component for object-based video coding schemes such as MPEG-4. A fast and robust video segmentation technique, which aims at e cient foreground and background separation via e ective combination of motion and color segmentation modules is proposed in this work. First, a non-parametric gradient-based iterative color(More)
A smart interactive video object generation (SIVOG) system is proposed in this work. SIVOG provides a semantic layer to interact with the user. It interprets user’s input and chooses proper processing algorithms to extract the object. The proposed system is evaluated for several typical MPEG4 test sequences. The quality of segmentation results and the(More)
A fast and accurate unsupervised video segmentation technique is proposed in this paper to generate a binary mask of moving objects for MPEG-4 object-based video coding. The algorithm exploits the color feature in the L?u?v? space, and combines it with the motion feature to separate moving objects from the background. To be more speci c, a non-parametric(More)
A digital color image quality metric is proposed in this work based on the characteristics of the human visual system (HVS). Chromatic coordinates are transformed from spectral cone absorption responses to the opponent-color space. The sensitivity thresholds in each of the color space axes are measured and visual masking models are provided and(More)
