چکیده

This paper proposes an algorithm for offline recognition of handwritten characters, especially effective for large set characters such as Korean and Chinese characters. The algorithm is based on a template matching method which is easy to implement but suffers from low recognition performance. Two strategies has been developed to improve the performance of the template matching: one is multi-stage preclassification and the other is pairwise reordering. Effectiveness of the algorithm has been proven by an experiment with a handwritten Korean character database named PE92, where 86.0% of recognition accuracy and 15 characters per second of processing speed have been obtained.

A New RSTB Invariant Image Template Matching Based on Log-Spectrum and Modified ICA

Template matching is a widely used technique in many of image processing and machine vision applications. In this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to Rotation, Scale, Translation and Brightness (RSTB) changes. For this purpose, we adopt the idea of ring projection transform (RPT) of image. In the proposed algorithm, two novel s...

Evaluation of Similarity Measures for Template Matching

Image matching is a critical process in various photogrammetry, computer vision and remote sensing applications such as image registration, 3D model reconstruction, change detection, image fusion, pattern recognition, autonomous navigation, and digital elevation model (DEM) generation and orientation. The primary goal of the image matching process is to establish the correspondence between two ...

Synthetic Aperture Radar Automatic Target Recognition with Three Strategies of Learning and Representation

This paper describes a new architecture for synthetic aperture radar (SAR) automatic target recognition (ATR) based on the premise that the pose of the target is estimated within a high degree of precision. The advantage of our classifier design is that the input space complexity is decreased with the pose information, which enables fewer features to classify targets with a higher degree of acc...

Fast Template Matching Method Based on Optimized Metrics for Face Localization

Recently, Template matching approach has been widely used for face localization problem. Normalized Crosscorrelation (NCC) is a measurement method normally utilized to compute the similarity matching between the templates and the rectangular blocks of the input image to locate the face position. However, the NCC metric is always suffering to locate the face especially in the images with illumin...

High-speed object matching and localization using gradient orientation features

In many robotics and automation applications, it is often required to detect a given object and determine its pose (position and orientation) from input images with high speed, high robustness to photometric changes, and high pose accuracy. We propose a new object matching method that improves efficiency over existing approaches by decomposing orientation and position estimation into two cascad...
