Studies show that refining real-world categories into semantic subcategories contributes to better image modeling and classification. Previous image sub-categorization work relying on labeled images and WordNet’s hierarchy is not only laborintensive, but also restricted to classify images into NOUN subcategories. To tackle these problems, in this work, we exploit general corpus information to a...

A new class of burst-error-correcting codes and its application to PCM tape recording systems, Proof of Theorem 1. Let j 1 < j 2 < : : : < j s be a sequence consisting of all indexes 0 < j r h such that a j 6 = a j?1 ; note that j s = r h , and deene j s+1 = j s + 1. Fix T to a value less than or equal to r v. For every 1 ` s we have,

Abstract Due to chromatic aberration, blue images are defocused when the eye is focused middle of visible spectrum, yet we normally not aware blur. The suffers from monochromatic aberrations which degrade optical quality all projected on retina. combination and additive these may interact improve image quality. Using Adaptive Optics, investigated visual effects correcting viewing polychromatic ...

This paper presents a model for correcting the effects of barrel and pincushion lens distortion that preserves the scale of the captured image. This is significant as the model is able to correct for a practical range of the aforementioned types of lens distortion while maintaining the scale helps minimize the loss of the corrected image’s resolution. The functional inverse of the model is deri...

Within the framework of refining an articulatory model, articulatory data were collected using MRI, video and X-ray. A set of two-to-three dimensional rules were derived from the axial and coronal MRI images and applied to midsagittal X-ray images. The acoustic performance of the rules was evaluated by synthesizing observed and predicted area functions.
