# Matching and Measurement

| ![](assets/images/home/easyobject.webp)   | [EasyObject](easyobject/index.html.md) obtains information about distinct objects (blob analysis), identifies them using connected component labeling, then sorts and selects them according to their geometric features.                                          | - [Using](easyobject/index.html.md)<br/>- [Reference](../../reference_manual/matching_and_measurement/easyobject/index.html.md)<br/>- [Code snippets](../../resources/code_snippets/matching_and_measurement/easyobject/index.html.md)   |

| ![](assets/images/home/easygauge.webp)    | [EasyGauge](easygauge/index.html.md) 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](easygauge/index.html.md)<br/>- [Reference](../../reference_manual/matching_and_measurement/easygauge/index.html.md)<br/>- [Code snippets](../../resources/code_snippets/matching_and_measurement/easygauge/index.html.md)   |
| ![](assets/images/home/easyfind.webp)     | [EasyFind](easyfind/index.html.md) 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](easyfind/index.html.md)<br/>- [Reference](../../reference_manual/matching_and_measurement/easyfind-library.html.md)<br/>- [Code snippets](../../resources/code_snippets/matching_and_measurement/easyfind/index.html.md)   |
| ![](assets/images/home/easymatch.webp)    | [EasyMatch](easymatch/index.html.md) 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](easymatch/index.html.md)<br/>- [Reference](../../reference_manual/matching_and_measurement/easymatch-library.html.md)<br/>- [Code snippets](../../resources/code_snippets/matching_and_measurement/easymatch/index.html.md)   |
