Corner feature point detection with both the high-speed and high-quality is still very demanding for many real-time computer vision applications. The Harris and Kanade-Lucas-Tomasi (KLT) are widely adopted good quality corner feature point detection algorithms due to their invariance to rotation, noise, illumination, and limited view point change. Although they are widely adopted corner feature point...
In this paper, a novel fast Gaussian blurring method that uses look-up table (LUT) is presented for creating a real time difference of Gaussian (DoG) pyramid. The LUT for fast and accurate Gaussian blur is obtained from the values calculated from one-dimensional(1D) Gaussian elements and pixel values of image. To evaluate the method, computation time and similarity with a conventional two-dimensional(2D)...
This paper presents a novel template matching method to efficiently match and search image patterns. The method using concentric sampling structures, boosting process, and coarse-to-fine framework, differs from the traditional pattern matching schemes of time-exhausting correlation. The time complexity at searching stage is invariant to the dimension of concerned patterns. The rotation-invariant collection...
