Embodiment 1
[0017] Embodiment one, see figure 1 As shown, an image attention target semantic segmentation method based on fMRI visual function data DeconvNet includes the following steps:
[0018] Step 1. Collect fMRI visual function data of subjects stimulated by natural scene images, train a deep convolutional neural network model from stimulus images to fMRI visual function data, and a linear mapping from fMRI visual function data to target categories Model, which maps the trained deep convolutional neural network model to a linear mapping model to optimize the network model;
[0019] Step 2. Construct a deconvolution deep network model symmetrical to the deep convolutional neural network optimized by the network model, and optimize the deconvolution deep network model by using the fMRI visual function data and the semantic segmentation results corresponding to the stimulus images. Obtain the mapping from fMRI visual function data to pixel-by-pixel semantic segmentation results, and o...
