Figure 6.
Four elbow X ray images are shown in the top row labelled Reference H R 0060, D i V A Net, S Mixer t, and Ours. Each image displays the same elbow joint region in a similar rotated orientation. The bottom row shows gradient maps labelled H R Gradient, D i V A Net Gradient, S Mixer Gradient, and Ours Gradient. Each gradient map represents edge intensity patterns of the corresponding top image. A vertical scale bar appears at the right of the gradient row with values 0, 100, 200, and 300.Histogram of oriented gradients (HOG) as a visualization feature to display the edge gradient information of the SR images. We presented 0060 samples with an upsampling factor, incorporating DiVANet and ShuffleMixer (tiny) as benchmark comparisons. Best viewed in color
