    Abstract: An automatic system for the inspection of a plurality of protruding features of an object employing computer vision. The system examines the position of a tip of the feature and compares it with an ideal position to determine if the object is defective or not. The position of the tip is calculated from a cluster of perceived pixels above a certain threshold of light intensity. In one embodiment, mathematic morphological manipulations of the gray scale perceived pixels assists in the analysis of the positions of the protruding features. The system provides an objective, fast and economical method of inspecting objects, such as electronic packages having a plurality of leads protruding therefrom.
