Patent number: 11983910Abstract: A first decoder obtains a region including an object targeted for recognition based on a feature map obtained by performing convolutional processing on a processing target image. Next, the first decoder obtains, from the feature map, a partial feature map of a portion corresponding to the obtained region including the object targeted for recognition. Then, a second decoder obtains pixels corresponding to the object targeted for recognition based on the partial feature map. This reduces the amount of calculation required for decoder units included in a neural network.Type: GrantFiled: May 11, 2021Date of Patent: May 14, 2024Assignee: Canon Kabushiki KaishaInventors: Takuya Ogawa, Motoki Ikeda
