Feature Extraction to Polar Image
Some algorithms of feature extraction in existing literature studied for image processing was the gray image with one-dimensional parameter. However, some feature points’ extraction for three-dimensional color of polar image, such as the color edge extraction, inflection points, and so on, was urgently to be solved a polar color problem. For achieving quickly and accurately the color feature ex...
متن کاملVibratory Image Feature Extraction Based on Local Log-Polar Symmetry
We propose a feature extraction method for a newly developed vibratory image sensor. The proposed method extracts a local log-polar symmetry as image feature. In this article, it is shown that log-polar symmetric patterns include well-known characteristic points such as edges, corners, peaks, and so on. The principle of our method is as follows: a periodic vibration of an image sensor modulates...
متن کاملPrimal sketch feature extraction from a log-polar image
We present a novel approach 1 for extracting primal sketch features (edges, bars, blobs and ends) from a log-polar image. Symmetry operators and a PCA pre-processing module precede a set of neural networks that learn the feature’s class and contrast. Experiments show the process accurately extracts the desired feature-based image description.
متن کاملImage Feature Extraction Acceleration
Image feature extraction is instrumental for most of the best-performing algorithms in computer vision. However, it is also expensive in terms of computational and memory resources for embedded systems due to the need of dealing with individual pixels at the earliest processing levels. In this regard, conventional system architectures do not take advantage of potential exploitation of paralleli...
متن کاملFeature Extraction for Image Mining
Due to the digitization of data and advances in technology, it has become extremely easy to obtain and store large quantities of data, particularly Multimedia data. Fields ranging from Commercial to Military need to analyze these data in an efficient and fast manner. Presently, tools for mining images are few and require human intervention. Feature selection and extraction is the pre-processing...
