Ray-tracing, can produce high-quality images, however, the use of ray-tracing has been limited due to its high demands on computational power and memory bandwidth, especially in the case of satellite imagery. In this paper, we propose a scalable parallel ray tracing algorithm of satellite imagery on a cluster of multi-core architecture. The algorithm combines demand-driven and data-driven models in...
In this paper, we present a 3D X-Ray Transform based feature extraction and classification method for Digital Multi-focal Images (DMI). In such images, morphological information for a transparent specimen can be captured in the form of a stack of high-quality images, representing individual focal planes through the specimen's body. We present a method that can effectively exploit the entire information...
By the research on the characteristics of CCD temperature - noise, this paper designs a cooling CCD which uses a miniaturized refrigeration technique in order to meet the request of obtaining high-quality image in the dim light conditions. The design uses thermoelectric cooling technology and accomplishes the cooling design and optimization of refrigeration cavity with the assistance of Qfin. The...
A novel self-correction differential active pixel with redundancy is proposed to produce high-quality image in harsh environment. In order to avoid common-mode noise from environment and interference between digital signal and analog signal, a couple of differential outputs are generated and transferred by splitting the photodiode and readout transistors into two half-size parts. The performance of...
In this paper, we present a motion-blur-free camera system using multi-exposed images. The proposed camera system captures three frames successively from the same scene at long-short-long exposure times. In the proposed system, the high-quality image is obtained by combining the shape information of the object in an under-exposed image captured at the short exposure time and the color information...
Summary form only given. De-interlacing, scaling, frame rate conversion, compression artifact removals are currently major video processing challenges to produce high quality images for HD TV displays. Recovering high resolution images from degraded or lower resolution videos requires adaptive geometric filtering and interpolation in space and time, at very high data rate. Finding appropriate image...
The objective of this work is to automatically generate a large number of images for a specified object class (for example, penguin). A multi-modal approach employing both text, meta data and visual features is used to gather many, high-quality images from the Web. Candidate images are obtained by a text based Web search querying on the object identifier (the word penguin). The Web pages and the images...
