Crop Image

This is a screen analysis tool that the author uses to specify the screen element himself if the part that is not recognized as an OD or OCR tool needs to be used as a screen element.

The author directly selects the screen element by dragging and dropping directly from the device screen, and the selected screen element analyzes and compares the image of the area using Feature Matching technique.

There are several precautions when creating screen elements with Crop Image.

1. Complex images have a higher recognition rate than simple images. Because the feature points of an image are extracted and used as a comparison object, the more complex images are, the higher the recognition rate is because the more feature points are extracted than simple images.

2. Specifying that the desktop is not included when selecting an image increases recognition. This is because the higher the proportion of monochromatic regions, the lower the feature point ratio. Compared to the designated desktop area of your desktop, Specifying the desktop area to be held to a minimum has a higher recognition rate.
