Patent number: 11482001Abstract: In a current image processing environment, providing feedback for a user operation is slow, and a user cannot confirm the result of the operation in real time. Thus, the user interrupts the operation every time the user confirms the feedback, and a time period for performing image processing is long. An image processing device includes a guidance information generator. The guidance information generator acquires trajectory information to be used to segment an image object on an image input from a user, generates guidance information indicating a segmentation region desired by the user based on the trajectory information, and presents the segmentation region based on a user's intention in real-time. The guidance information generator provides a function of smoothly continuously segmenting an image object.Type: GrantFiled: February 24, 2020Date of Patent: October 25, 2022Assignee: HITACHI, LTD.Inventors: Ziwei Deng, Quan Kong, Naoto Akira, Tomokazu Murakami
