Abstract

In this paper, the original N-FINDR algorithm is implemented in four different versions: 1) parallel mode using the data after dimensionality reduction; 2) parallel mode using all the original bands; 3) sequential mode using the data after dimensionality reduction; 4) sequential mode using all the original bands. We will analyze the performance discrepancy among these versions. Based on experimental evaluation and comparison, instructive recommendations in implementation strategy for practical applications are provided.
