# ImageParameter Parameters

The `ImageParameter` object configures parameters for image processing stages in Dynamsoft Capture Vision, including grayscale conversion, enhancement, binarization, texture detection, and more.

## Example JSON

## Hierarchical Structure

This tree shows one `ImageParameter` object inside `ImageParameterOptions`.

`ApplicableStages` defines stage objects. Stage-scoped parameters are constrained by the `Stage` value in each item.
