EasyFind - Matching Geometric Patterns¶

EasyFind is a pattern matching library that allows users to learn and identify given patterns in an image.

Process¶

EasyFind learns your pattern from one or several images or a set of shapes.

The pattern is a set of all the feature points that EasyFind computes during the learning process:
- EasyFind can extract these points from a bitmap representation of the pattern (see Learn a Pattern from Image(s)).
- Or it can use the feature points that are directly given by geometrical shapes (see Learn a Pattern from Vectors).

EasyFind detects the instances of your pattern in your images as a vector of EFoundPattern ^.NET ^Python (see Find Matches).

Each EFoundPattern contains a Score, Center, Angle and Scale.
These EFoundPattern can be highly-degraded due to noise, blur, occlusion, missing parts or unstable illumination conditions.
- To optimize the find process, adjust the search parameters and check what EasyFind has found.
