The identification of ballistics specimens from imaging systems is of paramount importance in criminal investigation. Binarization plays a key role in preprocess of recognizing cartridges in the ballistic imaging systems. Unfortunately, it is very difficult to get the satisfactory binary image using existing binary algorithms. In this paper, we utilize the global and local thresholds to enhance the...
An automatic image processing method is proposed to extract vocal fold vibrations from high-speed digital imaging. Extracted regular vocal fold vibrations contribute to periodic voices, and irregular vocal fold vibrations contribute to aperiodic voices. The effects of image resolutions are investigated. This study combines the features of both image and voice signal processing and provides a valuable...
This paper proposes a free-viewpoint imaging method that can be used in a complicated scene such as an office room by using sparsely located cameras. In our method, a free-viewpoint image is generated from multiple image patches obtained by dividing observed images. The quality of the generated image strongly depends on how to divide the observed images. In an incorrect patch in the generated image,...
