Two-stream bidirectional long short-term memory for mitosis event detection and stage localization in phase-contrast microscopy images

Abstract

In this paper, we propose a Two-Stream Bidirectional Long Short-Term Memory (TS-BLSTM) for the task of mitosis event detection and stage localization in time-lapse phase contrast microscopy image sequences. Our method consists of two steps. First, we extract candidate mitosis image sequences. Then, we solve the problem of mitosis event detection and stage localization jointly by the proposed TS-BLSTM, which utilizes both appearance and motion information from candidate sequences. The proposed method outperforms state-of-the-arts by achieving 98.4% precision and 97.0% recall for mitosis detection and 0.62 frame error on average for mitosis stage localization in five challenging image sequences.
