EasyOCR: Optimized for Qualcomm Devices
EasyOCR is a machine learning model that can recognize text in images. It supports 80+ supported languages and all popular writing scripts.
This is based on the implementation of EasyOCR found here. This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the Qualcomm® AI Hub Models library to export with custom configurations. More details on model performance across various devices, can be found here.
Qualcomm AI Hub Models uses Qualcomm AI Hub Workbench to compile, profile, and evaluate this model. Sign up to run these models on a hosted Qualcomm® device.
