ePillID Benchmark Open In Colab

PWC

This repository contains data and code for ePillID - a benchmark for developing and evaluating computer vision models for pill identification. The ePillID benchmark is designed as a low-shot fine-grained benchmark, reflecting real-world challenges for developing image-based pill identification systems.

The characteristics of the ePillID benchmark include:

  • Reference and consumer images: The reference images are taken with controlled lighting and backgrounds, and with professional equipment. The consumer images are taken with real-world settings including different lighting, backgrounds, and equipment. For most of the pills, one image per side (two images per pill type) is available from the NIH Pillbox dataset.

Examples of reference and consumer images in ePillID

  • Low-shot and fine-grained setting: 13k images representing 9804 appearance classes (two sides for 4902 pill types). For most of the appearance classes, there exists only one reference image, making it a challenging low-shot recognition setting.

ePillID data distribution

  • The best performing model at the time of publication is a multi-head metric learning approach. Following a CNN encoder, a bilinear transformation layer is used to represent fine-grained embeddings.
