- Abstract:
-
Resting-state functional magnetic resonance images are a series of three-dimensional (3D) images that change over time. The existing 3D convolution processes 3D image data or two-dimensional image and time-dimensional data, but it cannot effectively fuse the time axis information of a resting-state functional magnetic resonance image. To resolve this, a new four-dimensional (4D) convolutional neural network (CNN) recognition model is proposed in this paper. Specifically, by performing a 4D convolution using a 4D convolution kernel on the input functional magnetic resonance imaging, features are spatially and temporally extracted from the functional magnetic resonance image of a patient with autism, thereby capturing information about the changes in the image’s time series. The developed model generates multiple information channels from the input image, and the final feature representation combines information from all channels. The experimental results show that to ensure the generalization performance of the model, the method fuses the global information of the functional image and collects its trend information over time, consequently solving the classification problem of 3D image changes with time using a CNN.
