Abstract
(EN) A target detection method based on stream convolution. On the basis of group convolution, the stream convolution uses a channel path aggregation operation, i.e., connecting a current subgroup input feature to a subgroup output feature of a previous layer to obtain a subgroup output feature of a current layer, and improving feature information flow among the subgroups. The target detection method based on the stream convolution not only effectively reduces network parameters and calculation costs, but also further improves the accuracy of target detection.
(FR) L'invention concerne un procédé de détection de cible fondé sur une convolution de flux. Sur la base d'une convolution de groupe, la convolution de flux utilise une opération d'agrégation de trajets de canal, c'est-à-dire la connexion d'une caractéristique d'entrée de sous-groupe en cours à une caractéristique de sortie de sous-groupe d'une couche précédente pour obtenir une caractéristique de sortie de sous-groupe d'une couche en cours, et améliorer le flux d'informations sur les caractéristiques parmi les sous-groupes. Le procédé de détection de cible fondé sur la convolution de flux réduit non seulement efficacement les paramètres de réseau et les coûts de calcul, mais améliore en outre la précision de détection de cible.
(ZH) 一种基于流卷积的目标预测方法,所述流卷积在分组卷积的基础上,利用通道路径聚合操作,即连接当前子分组输入特征与上一层子分组输出特征去得到当前层子分组输出特征,去加强各子分组之间的特征信息流通。基于流卷积的目标检测方法不仅有效减少了网络参数与计算成本,而且使得目标检测精度得到进一步提升。
