Schematic diagram of the effect of view-proxy loss. (a) Graph chart diagram without view-proxy loss. The graph chart diagram (grey connected circles) without view-proxy loss is formed, in which points corresponding to actual 4CV (surrounded by the blue line), actual 3VTV (surrounded by the red line), and other planes are randomly mixed. (b) Graph chart diagram with view-proxy loss. The stars denote the coordinates for the ideal 4CV (blue) and 3VTV (red). The squares denote corresponding points to the synthesized barcode-like timelines for 4CV (blue) and 3VTV (red). The view-proxy loss (orange bidirectional arrows) considers the loss between the stars and squares. As a corollary of optimizing the view-proxy loss, the grey points surrounded by the blue or red lines are attracted to their respective specified coordinates. As a result of optimizing the view-proxy loss, the graph chart diagram is expected to be untangled.
