Recognition Using Multi-stage Deep Learning
Fig. 1. Definition of body sections. Human body is divided into 12 continuous parts. Each parts may cover different ranges due to the variability of anatomies (Color figure online). In…
Detection of the Uterus and Fallopian Tube Junctions in Laparoscopic Images
Fig. 1. Laparoscopic images of the uterus. FU-junctions are shown in blue and green for left and right respectively. The detection difficulty comes from ligament junctions, variation in the Fallopian…
Transfer Segmentation
Fig. 1. Illustration of keypoint transfer segmentation. First, keypoints (white circles) in training and test images are matched (arrow). Second, voting assigns an organ label to the test keypoint (r.Kidney)….
PET Reconstruction with Sparse Image Representation and Anatomical Priors
between two points i and j in the image domain, defined by (1)where is the spatial Euclidean distance, is the image intensity similarity, and these two different measures are combined…
Manifold Alignment of Functional Network Structures via Joint Diagonalization
consists of N voxels observed at T time points. The functional architecture of a brain state can be modeled as a connectivity graph G with vertices V representing the voxels,…
