MIMO-NET: A MULTI-INPUT MULTI-OUTPUT CONVOLUTIONAL NEURAL NETWORK FOR CELL SEGMENTATION IN FLUORESCENCE MICROSCOPY IMAGES

We propose a novel multiple-input multiple-output convolution neural network (MIMO-Net) for cell segmentation in fluorescence microscopy images. The proposed network trains the network parameters using multiple resolutions of the input image, connects the intermediate layers for better localization and context and generates the output using multi-resolution deconvolution filters. The MIMO-Net allows us to deal with variable intensity cell boundaries and highly variable cell size in the mouse pancreatic tissue by adding extra convolutional layers which bypass the max-pooling operation. The results show that our method outperforms state-of-the-art deep learning based approaches for segmentation.
