A new measurement on camera shakes featuring a combination of a gyro sensor and signal processing is reported. For higher accuracy, shake movements are separated into rotational and translational motions. Advanced quantitative analysis on image quality is also presented considering the effect from translation which was not discussed previously.
It is widely acknowledged that computer is powerful tool to improve the quality of life of the people with disability. One problem is how the user manipulates the computer using suitable input device designed for him or her. This paper proposes tow pointing devices based on vision for the people with disability as input devices. These devices detect the position of the marks attached on the users...
Markov random field (MRF) models are a powerful tool in machine vision applications. However, learning the model parameters is still a challenging problem and a burdensome task. The main contribution of this paper is to propose a locally adaptive learning framework. The proposed learning framework is simple and effective learning framework for translation-variant MRF models. The key idea is to use...
Authors are developing a rotorcraft with autonomous controller for the remote sensing of agricultural fields. Accurate position sensing is essential to the development of the autonomous control system. One major method for the position sensing is to use the image processing technique. Among the image processing techniques labeling processing is most practical and is widely used for detecting the position...
We developed a communication device to use slight movement for serious disabled. This device is developed mainly for patients suffering from ALS or a cerebral infarction. They often have communication difficulty because of deterioration of muscular functions. A feature of this device is it detects slight movements of user's finger, eyes or lips. Because of this feature, it is quite easy even for serious...
At present the diagnosis of melanoma is mainly performed based on the experience of each doctor. The doctors need some objective measure for diagnosis of melanoma and nevus. But there are few researches on objective index for the diagnosis. This workr deals with features of melanoma and nevus for computer diagnosis. First, we extracted the contour of lesions with image processing. One hundred five...
