Gray scaling is richer than Binarizing as it shows the image as a combination of different intensities of Gray. . A step has three properties that define how it will be treated by the algorithm running engine: Tag: unique identifier of a step, typically the name of the function associated with this step, followed by a numeric index accounting for possible multiple uses of the same function; Active: a Boolean (true/false) value indicating if this step is to be considered or not when running the algorithm (to allow maximum flexibility in testing algorithms); InParamLinks: a list of strings linking this step functions parameters to values returned by functions in previous steps, wherever the case (not a typical situation, but implemented for flexibility). ORB is an efficient alternative to SIFT or SURF algorithms used for feature extraction, in computation cost, matching performance, and . Method #1: Grayscale Pixel Values as Features The simplest way to create features from an image is to use these raw pixel values as separate features. several techniques or approaches, or a comprehensive review paper with concise and precise updates on the latest ORB A good example of feature detection can be seen with the ORB (Oriented FAST and Rotated BRIEF) algorithm. In pattern recognition and in image processing, feature extraction is a special form of dimensionality reduction.
