## Introduction

This is key feature of ID intelligence API. This helps in image quality analysis, allowing it to assess the quality of ID card images. It can evaluate factors such as sharpness, text quality, brightness, and compression quality. By analyzing these parameters, it provides a score indicating the overall image quality.

## API Details

You need to pass `performImageQualityAnalysis` as True in order to use this feature. You can also set your threshold of acceptance as per your business usecase. Use field `imageQualityThreshold` to set threshold as per your business requirement. 

We have mentioned only this feature in the below Curl. For Curl with complete features, refer the [ID Intelligence](docId:9dWPKYoaeY2mFiYs4oKlD)
