Recently, the opportunity to treat images has increased. Most of the images are large, so they are usually compressed with JPEG and MPEG, which is a major compression standard. JPEG and MPEG use DCT (Discrete Cosine Transform) for transform. The DCT causes more and more blocky noise as the compression rate is set higher and higher. The images taken in the past are usually strongly compressed. We propose...
This paper presents an entirely new method which achieves precise length measurement of products on conveyor belt at high speed. Recently, the automatic length measurement of products in motion is coming to assume greater importance in industrial fields. Then, making the best use of the conventional length measurement on a conveyor, we propose a new length estimation method for moving products with...
In mobile and ubiquitous computing environments, acquisition of contextual information about a user situation is necessary to provide useful services. Although the definition of user context may change according to the situation or the service used, contextual information about who, where, and when are considered to be essential. We have built a test bed with multiple sensors: floor pressure sensors,...
