Contourlet-Based Edge Extraction for Image Registration
Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...
متن کاملAn Efficient Signature Extraction Method for Image Similarity Retrieval
The goal of similarity retrieval is to retrieve images that are similar to query image. Good access methods for large image databases are very important for efficient retrieval. The 2D B-string-based and unique-ID-based signature methods can provide four kinds of similarity retrieval, object and type-i, where 0 ≤ i ≤ 2, and can distinguish 169 spatial relationships. However, 169 spatial relatio...
متن کاملImage Variational Decomposition Based on Dual Method
In the paper, we firstly recommend a new variational model for image decomposition into cartoon and texture or noise by introducing a new function in Sobolev space, in order to overcome the inconsistency between the theoretical model and numerical simulation. Secondly, we prove the existence of minimal solutions of the improved ROF energy functional. Subsequently, we also introduce two addition...
متن کاملMicro-Doppler Processing for Ultra-Wideband Radar Data
In this paper, we describe an operational pulse Doppler radar imaging system for indoor target localization and classification, and show how a target’s micro-Doppler signature (μDS) can be processed when ultra-wideband (UWB) waveforms are employed. Unlike narrowband radars where time-frequency signal representations can be applied to reveal the target time-Doppler frequency signatures, the UWB ...
