+# High Resolution Pose Estimation
+
+This folder contains sample applications that demonstrate various parts of the functionality provided by the High Resolution Pose Estimation algorithm provided by OpenDR.
+
+More specifically, the applications provided are:
+
+1. demos/inference_demo.py: A tool that demonstrates how to perform inference on a single high resolution image and then draw the detected poses. 
+2. demos/eval_demo.py: A tool that demonstrates how to perform evaluation using the High Resolution Pose Estimation algorithm on 720p, 1080p and 1440p datasets. 
+3. demos/benchmarking_demo.py: A simple benchmarking tool for measuring the performance of High Resolution Pose Estimation in various platforms.
