Image enhancement is one of using in various digital signal processing areas. Advances in microcontrollers DSP boards and computers have been developed traditional algorithms to improve the quality of the resulting image. This paper aims to present the contrast enhancement using weighted bi-histogram equalisation. In additional this technique must use two weighted factors which is calculated by the histogram distribution ratio. Likewise an original image will be equalised by the modification of the probability density function of the gray levels. As the experimental results the contrasts of resulting images are improved for robot vision implement and human perception including absolute mean brightness error (AMBE) limitation.

The purposes of the research were 1) to study the consumers’ perception of the brand image of Toyota Camry Hybrid in Bangkok and 2) to compare demographic characteristics with consumers’ perception of the brand image of Toyota Camry Hybrid in Bangkok. The data was collected by using questionnaires completed by 200 respondents who bought Toyota Camry Hybrid from authorized dealers in Bangkok.Data analysis employed frequency average percentage and standard deviation. Statistic used for testing the independent sample was the independent t-test and the F-test to determine the difference with the one-way analysis of variance. The LSD was used to find a statistical difference. The study presented the following results: Consumers’ demographic in the research study were males (67.0%) age between 41-45 (38.5%) university graduates (85.5%) salaried employees (44.5%) and average monthly income between 50001-60000 baht (36.0%) The survey showed that consumers’ perception of the brand image of Toyota Camry Hybrid was the most brand recall in the highest level. Three top brands were Toyota Camry Hybrid (40.0%) Benz C 180 (31.0%) and BMW Series 5 (26.0%). Consumer’s brand recognition that was medium-size car was Toyota Camry Hybrid (100.0%). Brand image assessment of the Toyota Camry Hybrid that was the most brand recall to high technology was 99.5 percent and the perception of consumers towards the Toyota Camry Hybrid brand image overall was at high level. Having considered in each aspect strength and favorability of brand associations and uniqueness of brand associations were at the highest level and marketing communication was at the high level.The hypothesis testing showed that different age education and occupation of consumers had statistically significant differences at the level of .05 on their perception of Toyota Camry Hybrid brand’s image. On the contrary difference in gender and monthly income had no statistical significance for their perception of Toyota Camry Hybrid brand image.

This research report is manipulated that summarized the moment of research project in the subject of “The optimal image processing for paddy studies: Variety classification and rice kernel damage inspection”. This project had been take time in 12 mounts. We focused on rice variety classification and rice kernel damage inspection. We also investigated the apparent friction of rice surface. Results showed that area and size were the quantities that have the potential to classify rice variety and also rice kernel damage inspection. In addition we also found that geometric mean diameter performed characteristic to apparent friction of rice surface in kerosene. These results have the potential to be the basis information in terms of developing instrument for quality control and variety classification of cereal.

In present there are widely use robot in many fields. Mobile robot can help us in several task such as moving to toxic area risk area or explosion area mine. Movement control can be used in many ways. This paper proposed mobile robot that movc by wheels. It move to previous defined picture. By using small camera process an images and check it that is the previous one by using neural network. If it is robot will move toward to that picture. The movement is in flat plane. If that defined picture is not in center robot will move to left or right depend on its position until it is on center. This paper proposed image processing only.

The objectives of this research were to study and compare viewpoints of employers regarding current image and desired image of Rajamangala University of Technology Phra Nakhon graduates. Survey research methodology was exploited by distributing questionnaires to sample group of 247 employers. Thereafter data was analyzed by t-test at statistically significant level of 0.05 for hypothesis testing. The results were as follows: graduates had current image at a high level. Graduates with good mental health as well as cheerful and happy graduates had the highest mean value while graduates with foreign language knowledge and ability had the lowest mean value. The result also showed that desired image of graduates were high. Good moral and ethic graduates had the highest mean value whereas graduates with foreign language knowledge and ability had the lowest mean value. By comparing current image to desired image the study found that all images were significantly different at the level of 0.05 except good mental health cheerful and happy graduates.
