An automated approach is proposed for a microassembly task, which is to insert a 10 µm diameter glass tube into a 12 µm diameter hole in a silicon substrate, and bond them together with ultraviolet (UV) curable adhesive. Two three-degree-of-freedom micromanipulators are used to move the glass tube and the dispensing needle, respectively. Visual feedback is provided by an optical microscope. The angle...
Compositing is one of the most common forms of digital image tampering. In this paper, we present a passive approach to detect composite JPEG images by measuring inconsistencies of blocking artifacts. Firstly, double-compression detection is performed to estimate the primary quality factor. Secondly, the blocking artifacts ratio mapping is extracted in the DCT domain via computing the blocking artifacts...
Real-time gesture recognition is mandatory for gesture based human-robot natural interaction. Several glove-based approaches are introduced for this purpose, but they are un-natural and force user to wear some cumbersome glove. This paper presents a vision-based gesture recognition method for human-robot interface. Hand poses and face are detected using multiple feature-based template matching techniques...
