Qianhui Liu, Yan Zhang, Gongping Yang

Abstract: Highlights•Proposing an integrated detection and counting model for unopened cotton bolls.•The multi-receptive field extraction module reduces the loss on features.•The multi-scale residual block enhances the extraction of small targets.•The small target detection layer improves the detection accuracy.
