A Block Object Detection Method Based on Feature Fusion Networks for Autonomous Vehicles

Figure 4

Different blocking strategies for 1920×1200 images. The same color represents blocks of the same size, and different colors represent blocks of different sizes. The 300×300 block strategy yields two different sizes of 300×300 and 120×300 blocks, including 24 blocks of 300×300 and 4 blocks of 120×300, as depicted in (a). Similarly, the 400×400 block strategy yields two different sizes of 400×400 and 320×400 blocks, including 12 blocks of 400×400 and 3 blocks of 320×400, as depicted in (b). Moreover, the block strategies of 500×500 and 600×600 are the same as those of Figures (a) and (b), as shown in (c) and (d).
