    This paper proposes a method to generate realistic hair model for individuals based on image processing, . The analysis and recognition of hair strands by image processing provide valuable data, particularly hair outline and the flow direction of the hair for the modeling of realistic hair model for individuals. The outline region acquired through image processing ensures that the generated hair strands fall neatly into the hair region. In the case of hair strands falling out of the outline region, weights are added on reduced at the interconnected masses in order to move the strand back into the hair legion. The lines extracted by image processing serves as guide-lines directing the hair strands to point in the desired direction. Through this algorithm, hair model with close resemblance to the individual can be achieved. This realistic hair model can find many applications in the generation of synthetic humans and creatures in movies, multimedia and computer game productions.

    This research proposes image-based hair modeling algorithm that is effective at producing a realistic hair model for virtual characters in the world of virtual reality, movies, television commercials, and simulation games. To create a realistic and physically accurate hair model, the importance of hair cutting and bending must he considered. The problems of cutting and bending are solved through the use of multiple images of a human model. Multiple hair images taken from different directions provide the cutting criteria. To calculate the bending angle, hair volume is produced from three images of the head taken from the right, back and top. This hair volume represents the real space volume where hair is found and guides the bending process until the hair strands are inside the hair volume. The use of the hair volume together with the hair-area-outlines produces a hair model that is not only realistic but also closely resembles the human model in the picture.One main advantage of this hair model is the ability to model hair for specific individuals which is very difficult to achieve with other methods.

     Numerous studies have been performed on casein micelles because they have characteristic structure and biological functions, and play important roles in processing of milk. More than twenty models have been proposed since Waugh proposed the first model of casein micelle in 1958. In this review, models of the casein micelle were divided into three groups of early stage, submicelle, and nanocluster modeles, and then their characteristics were described. Submicelle models of Slattery, Schmidt and Walstra had been accepted by many researchers. However, since Holt proposed the nanocluster model in 1992, most of the proposed models were modified nanocluster ones. We made discussions on the electron micrographs which played a key role in proposing the nanocluster models. Finally, we described whether it is possible to explain the changes in casein micelles during processing milk using the submicelle model of Schmidt, nanocluster models of Holt, Horne, and Dalglesish & Corredig. It is impossible to explain all phenomena which occur in casein micelles during processing of milk using any models. Further studies on casein micelles are needed.
