Optimization of Real-Time Object Detection on Intel® Xeon® Scalable Processors

November 11, 2017

This publication demonstrates the process of optimizing an object detection inference workload on an Intel® Xeon® Scalable processor using TensorFlow. This project pursues two objectives: Achieve object detection with real-time throughput (frame rate) and low latency Minimize the required computational resources In this case study, a model described in the “You Only Look Once” (YOLO) project is used for object detection. The model consists of two components: a convolutional neural network and a post-processing pipeline. In this work, the original Darknet model is converted to a TensorFlow model. First, the convolutional neural network is optimized for inference. Then array programming with NumPy and TensorFlow is implemented for the post-processing pipeline. Finally, environment variables and other configuration parameters are tuned to maximize the computational performance. With these optimizations, real-time object detection is achieved while using a fraction of the available processing power of an Intel Xeon Scalable processor-based system. [...]
