It is highly necessary to merge high spatial resolution panchromatic images with high spectral resolution multispectral images in image processing tasks and thematic applications. WorldView-3 (WV-3) imagery was investigated for generating pan-sharped multispectral imagery. Brovey and NNDiffuse pan sharpening algorithms were comparatively used to perform the image fusion and the quality was also assessed...
In this paper, a circle object recognition method based on monocular vision for the home security robots is proposed. This vision system is able to process image and recognize a colored ball rapidly. The proposed method consists of two submodules, which are the object segmentation module and the circle detection module. In order to implement the object segmentation, the color feature is applied to...
This work investigate the full energy and total efficiencies of large volume CdZnTe detectors. The efficiencies of three 20 mm × 20 mm × 15 mm pixelated CdZnTPe detectors were measured using the H3Dv2 Application Specific Integrated Circuit (ASIC) readout system developed by Brookhaven National Laboratory with un-collimated 241Am, 137Cs, and 60Co sources. One detector was made by eV-Products while...
Distance learning is a learning style that can overcome the limitation of time and space. Because of the distance, teachers can not assess the achievement of affective domain teaching goal. If teachers can know the student's affective state through the learning system, they can overcome the difficult. The research applies the image recognition technologies to capture the face images of students and...
Learner attention affects learning efficiency. However, in many classes, teachers cannot assess the degree of attention of every student. When a teacher is capable of addressing inattentive students immediately, he can avoid situations in which students are inattentive. Many studies have analyzed student attentiveness by the applying of image detection technologies. If this mechanism can be applied...
Fingerprint recognition is one of the most important technologies of the biometrics identification. As a convenient, fast and security method for personal identification, it has been widely used in many fields. The edge detection is an important part of the Fingerprint recognition; it has a serious influence on the thinner and the character extraction of the images, and finally effects the matching...
