Matching and Measurement

	EasyObject obtains information about distinct objects (blob analysis), identifies them using connected component labeling, then sorts and selects them according to their geometric features.	Using Reference Code snippets
	EasyGauge assesses dimensions of objects to sub-pixel precision, detects edges, locates points and fits geometric models. If the field of view is calibrated, it also measures in physical units (mm, inch…) instead of pixels.	Using Reference Code snippets
	EasyFind locates patterns in an image based on a geometrical model from a reference pattern or template. Compared to EasyMatch, it is computationally fast, robust against noise, occlusion, blurring and illumination variations.	Using Reference Code snippets
	EasyMatch locates patterns in an image based on a pixel-by-pixel comparison with a reference pattern or template. It can be used for image registration or component placement inspection.	Using Reference Code snippets
