Objects Classification by Learning-Based Visual Saliency Model and Convolutional Neural Network

Figure 4

We collected eye-tracking data on 300 images from ten subjects. The first row is the sample of original images (a) in EDOC. Gaze tracking paths and fixation locations are recorded in the second row (b). The third row (c) heat maps show RoIs according to (b). A continuous ground truth (d) is found by convolving Gaussian over the fixation locations of all subjects.
