Abstract：This paper presents a method to remove the black edge of documents in Android system based on open source computer
vision library OpenCV. It introduces how to use OpenCV in Android, describes the specific steps of using JNI to call OpenCV
function, which should be considered in using the camera. It describes the key process of using Android NDK to generate sharing library.
The experimental results show that this Android application has good performance in removing black edge of documents in
different types under different scenarios.
