Phases in Pattern Recognition System

Phases in Pattern Recognition System

Phase 1: Convert images sounds or other inputs into signal data. Phase 2: Isolate the sensed objects from the background. Phase 3: Measure the object’s properties that are useful for classification. Phase 4: Assign the sensed object to a category. Phase 5: Take other considerations to decide on appropriate action....

Problems Solved by these Phases

Sensing: It deals with problem arises in the input such as its bandwidth, resolution, sensitivity, distortion, signal-to-noise ratio, latency, etc. Segmentation and Grouping: Deepest problems in pattern recognition that deals with the problem of recognizing or grouping together the various parts of an object. Feature Extraction: It deals with the characterization of an object so that it can be recognized easily by measurements. Those objects whose values are very similar for the objects are considered to be in the same category, while those whose values are quite different for the objects are placed in different categories. Classification: It deals with assigning the object to their particular categories by using the feature vector provided by the feature extractor and determining the values of all of the features for a particular input. Post Processing: It deals with action decision-making by using the output of the classifier. Action such as minimum-error-rate classification will minimize the total expected cost....
