Easy Find
Based on an innovative feature-point technology, EasyFind is designed to rapidly find one or more instances of a reference model in the image. Compared to normalized correlation, EasyFind features faster processing and improved robustness. It shows excellent performances when handling instances that are highly degraded due to noise, blur, occlusion, missing parts or unstable illumination conditions.
The Highlight Features
- Pattern matching using a feature point technology
- Fully automatic, fast and robust
- Invariant to rotation and scaling
- High tolerance to pattern degradation
- Support of “don’t care” areas
Key Features

Supports “don’t-care” areas which allows the creation of complex pattern shapes.

EasyFind to match only the areas that convey valuable information, resulting in faster processing and much improved robustness.

With an adjustable accuracy up to sub-pixel level, EasyFind reports very precise information about the instances found, such as their location, rotation angle, scale and matching score.

Supported by Neo Licensing System
