摘要
Automatically segmenting crops and weeds in the image input from cameras accurately is essential in various agricultural technology fields,such as herbicide spraying by farming robots based on crop and weed segmentation information.However,crop and weed images taken with a camera have motion blur due to various causes(e.g.,vibration or shaking of a camera on farming robots,shaking of crops and weeds),which reduces the accuracy of crop and weed segmentation.Therefore,robust crop and weed segmentation for motion-blurred images is essential.However,previous crop and weed segmentation studies were performed without considering motion-blurred images.To solve this problem,this study proposed a new motion-blur image restoration method based on a wide receptive field attention network(WRA-Net),based on which we investigated improving crop and weed segmentation accuracy in motion-blurred images.WRA-Net comprises a main block called a lite wide receptive field attention residual block,which comprises modified depthwise separable convolutional blocks,an attention gate,and a learnable skip connection.We conducted experiments using the proposed method with 3 open databases:BoniRob,crop/weed field image,and rice seedling and weed datasets.According to the results,the crop and weed segmentation accuracy based on mean intersection over union was 0.7444,0.7741,and 0.7149,respectively,demonstrating that this method outperformed the state-of-the-art methods.
