This paper describes a device for real-time expanding sign language images inserted in any TV programs by 2×2 scale factor. Bicubic interpolation is used as an image expansion method. The 2×2 scale factor simplifies the bicubic interpolation formula to just division by two operations which enables an efficient hardware implementation. As a prototype version, the proposed architecture is implemented...
As technology becomes the part of human life for decades, the relationship between human and computer called human-computer interaction (HCI) is important to study for improving the system to serve the human need. HCI can be applied in various areas including medical system which is valuable for the elder who is not able to walk or express the feelings by words. The intuitive approach is the development...
One of the major road traffic accidents is from an exhausted driver such as drowsiness and a lack of attention over driving. This paper presents a driver fatigue warning system using Kinect depth image, which monitors a driver attention and alerts driver while nodding off. Our algorithm transforms Kinect depth images into gradient images to detect driver face and applies Discriminative Random Regression...
This paper proposes an FPGA architecture for the 1-D forward integer transform of the High Efficiency Video Coding (HEVC), which is the latest video coding standard. The work presents a novel technique which makes the architecture able to compute transform of flexible input combinations. The architecture can support all transform sizes i.e. 4×4, 8×8, 16×16, and 32×32, and all possible input combinations...
A device capable of data logging on/off status of all lamps in a house or office room for the purpose of monitoring energy consumption is described. It is based on 3 components which are a CMOS digital camera, a card type computer board and a WiFi module. An image of the room is taken once every minute and transformed to a two level black and white version from which a simple lamp detection is operated...
This paper proposes a hand posture recognition as an assistive tool for elderly care. The system uses Haar-like feature, Principle Component Analysis (PCA), and simulation web server for detection, recognition, and alert by order. Our system interprets the hand sign captured by web camera and alerts a caregiver via smart phone. Besides, a caregiver can also periodically check needs of an elder from...
This paper presents a novel user interface with computer. We propose eye and face detection via Haar-like feature with Bilateral Total Variation based super-resolution to resize the low resolution eye image from web camera. The center of eye-pair detection is mapped to the mouse coordinates in computer screen. Left click and right click are controlled by blinking left eye and right eye, respectively...
This paper proposes quality analysis of multi-frame Super-Resolution. We compare three algorithms of multi-frame Super-Resolution such as Bilateral Total Variation, Dual-Dictionary, and Kernel based Principal Component Analysis (KPCA). This research focuses on solving the problem in difference texture images. We experiment on Baboon, Lena, Eye, and Access Road. The algorithms are applied on 16 frames...
