Document Image Retrieval and Removal of Perspective Distortion Based on Voting for Cross-Ratios
We propose a method of document image retrieval using digital cameras. The proposed method takes as input parts or the whole of documents acquired as queries by a digital camera, and retrieve document images that include the queries. For this purpose, it is required to solve the problem of “perspective distortion” of images, as well as to establish a way for matching parts of document images fl...
متن کاملPerceptual Image Distortion
In this paper we present a perceptual distortion mea sure that predicts image integrity far better than mean squared error This perceptual distortion measure is based on a model of human visual processing that ts empirical measurements of the psychophysics of spatial pattern de tection The model of human visual processing proposed involves two major components a steerable pyramid trans form and...
متن کاملModel Image Distortion
We present a new technique to register an object model with an observed image. Our technique uses the model to establish an image-to-model correspondence and, therefore, to facilitate the registration process. The model guides and constrains the matching process in order to reduce the inherent complexity of the problem and to increase the robustness and eeciency of the solution. We begin by rou...
متن کاملImage Distortion Maps
Subjects examined image pairs consisting of an original and a reproduction created using either JPEG compression or digital halftoning. Subjects marked locations on the reproduction that differed detectably from the original. We refer to the distribution of error marks by the subjects as image distortion maps. The empirically obtained image distortion maps are compared to the visible difference...
متن کاملMemory distortion: an adaptive perspective.
Memory is prone to distortions that can have serious consequences in everyday life. Here we integrate emerging evidence that several types of memory distortions - imagination inflation, gist-based and associative memory errors, and post-event misinformation - reflect adaptive cognitive processes that contribute to the efficient functioning of memory, but produce distortions as a consequence of ...
