Browsing and Placement of Multi-Resolution Images on Secondary Storage
نویسندگان
چکیده
Image decomposition techniques such as wavelets are used to provide multiresolution representations of images. The original image is represented by several coef-cients, one of them with visual similarity to the original image, but at a lower resolution. Several strategies are evaluated to store the image coeecients on parallel disks so that thumbnail browsing as well as image reconstruction can be performed eeciently. Disk simulation and experiments with real disks are used to evaluate the performance of these strategies. The results indicate that signiicant performance improvements can be achieved with as few as four disks by placing image coeecients based upon browsing access patterns.

Pseudo Zernike Moment-based Multi-frame Super Resolution
The goal of multi-frame Super Resolution (SR) is to fuse multiple Low Resolution (LR) images to produce one High Resolution (HR) image. The major challenge of classic SR approaches is accurate motion estimation between the frames. To handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...
متن کاملA multi-scale convolutional neural network for automatic cloud and cloud shadow detection from Gaofen-1 images
The reconstruction of the information contaminated by cloud and cloud shadow is an important step in pre-processing of high-resolution satellite images. The cloud and cloud shadow automatic segmentation could be the first step in the process of reconstructing the information contaminated by cloud and cloud shadow. This stage is a remarkable challenge due to the relatively inefficient performanc...
متن کاملMulti-frame Super Resolution for Improving Vehicle Licence Plate Recognition
License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...

Due to the differences between the visible and thermal infrared images, combination of these two types of images is essential for better understanding the characteristics of targets and the environment. Thermal infrared images have most importance to distinguish targets from the background based on the radiation differences, which work well in all-weather and day/night conditions also in land s...
