Feature Based Image Mosaic Using Steerable Filters and Harris Corner Detector

Research of Image Mosaic Algorithm Based on Harris Corner Detection

This paper studies the general steps and methods of the image matching technology. Using a set of optimized Harris corner detection algorithm, a similar measure extracting feature points by the maximum correlation coefficient to achieve accurate matching. Finally, the weighted smoothing is performed to realize the seamless splicing of the two images according to the bilinear interpolation of th...

Tifinagh Character Recognition using Harris Corner Detector and Graph Representation

In this article, a printed Tifinagh character recognition system is presented. It is composed of three main steps: pre-processing, features extraction and classification. In the pre-processing step, binarization, normalization and thinning are applied to enhance the quality of the image. In the feature extraction step, corners are extracted using Harris Corner Detection method then represented ...

Image Analysis using Orientation Space based on Steerable Filters

Image Mosaic Using FAST Corner Detection

The main concept behind the image mosaic is image registration. The image mosaic can be defined as the automatic alignment or registration of multiple images into larger aggregates with two simultaneous images having some similarities between them. Image registration is an important part of the image processing and computer vision. On the basis of analyzing two types of image registration, an a...

Image Mosaic Based on Phase Correlation and Harris Operator

In order to improve the insufficiency of harris corner, we present an auto-adjusted algorithm of image size based on phase-correlation. First, we detect the zoom relationship and translation co-efficiency between the images and modulate the unregistrated image’s scale to the same level as the original image. We obtain the Region of Interest (ROI) according to the translation parameter and then ...
