Convolution by sliding window
WebFinally, a depthwise separable convolution is introduced to each MDC block to reduce the computational cost. We conduct experiments on three datasets: DIOR, DOTA, and NWPU VHR-10. ... used sliding windows for object detection in RSIs. Shi Z et al. proposed a histogram of oriented gradient (HOG) feature for ship detection. It is computationally ... WebIts sliding window is equivalent to the convolution kernel. The Q, K, and V structure of the single-pixel neighborhood attention is shown in Figure 3. Neighborhood attention has a flexible sliding window mode and its acceptance field can grow flexibly under a dynamic moving window without additional element cyclic shift operations.
