Many approaches in computer vision require multiple retrievals of histograms for rectangular patches of an input image. In 2005 an algorithm to accelerate these retrievals was presented. The data structure utilized is called Integral Histogram, which was based on the well known Integral Image. In this paper we propose a novel approximating method to obtain(More)
BACKGROUND The glycan cell surface molecules, stage-specific embryonic antigen (SSEA)-1, -3 and -4 and tumor-rejection antigen (TRA)-1-60 and -1-81, are expressed in specific combinations by undifferentiated pluripotent cells, i.e. embryonic stem cells, induced pluripotent stem cells, embryonal carcinoma cells, primordial germ cells and embryonic germ(More)
Krüppel-like factor 4 (KLF4) is a transcription factor involved in many cellular and developmental processes such as terminal differentiation of cells and carcinogenesis. Mice lacking KLF4 die post-natally due to skin barrier deficiencies and exhibit several additional cellular defects. The adult rodent testis expresses high levels of Klf4 mRNA. Using in(More)
As multicore PCs begin to get the standard, it becomes increasingly important to utilize these resources. Thus we present a multithreaded realtime vision system, which distributes tasks to given resources on a single off-the-shelf multicore PC, applying an optimal-backoff scheduling strategy. Making use of an asynchronous data management mechanism, the(More)
BACKGROUND Embryonic stem cells (ESC) hold great promise for the treatment of degenerative diseases. However, before clinical application of ESC in cell replacement therapy can be achieved, the safety and feasibility must be extensively tested in animal models. The common marmoset monkey (Callithrix jacchus) is a useful preclinical non-human primate model(More)
The interaction of humans and robots has the potential to set new grounds in industrial applications as well as in service robotics because it combines the strengths of humans, such as flexibility and adaptability, and the strengths of robots, such as power and precision. However, for a successful interaction the safety of the human has to be guaranteed at(More)
Both clinical and experimental observations suggest that allograft rejection is a complex process with multiple components that are, at least partially, functionally redundant. Studies using graft recipients deficient in various genes including chemokines, cytokines, and other immune-associated genes frequently produce a phenotype of delayed, but not(More)
We present an effective and fast method for static hand gesture recognition. This method is based on classifying the different gestures according to geometric-based invariants which are obtained from image data after segmentation; thus, unlike many other recognition methods , this method is not dependent on skin color. Gestures are extracted from each frame(More)
The biological complexity of allograft rejection and alloantigen-independent mechanisms is poorly understood. Therefore, we analyzed four components of the biological response following transplantation by global gene analysis. A comparative and kinetic approach was used to identify gene expression profiles. Biological processes were assigned to genes(More)
