  • Publication number: 20210233648
    Abstract: Provided are a medical image processing apparatus, a medical image processing method, a program, and a diagnosis support apparatus that appropriately control whether or not to report reporting information of a medical image independently of a user operation. The above object is achieved by a medical image processing apparatus including a reporting control unit that performs control to bring reporting information included in a medical image into either a reporting state in which the reporting information is reported by a reporting unit or a non-reporting state in which the reporting information is not reported by the reporting unit. The reporting control unit brings the reporting information into the non-reporting state in a case where the medical image satisfies a non-reporting condition and brings the reporting information into the reporting state after a non-reporting time has elapsed from when the medical image does not satisfy the non-reporting condition.

  • Publication number: 20210150277
    Abstract: An object of the present invention is to provide an image processing method and an image processing apparatus that make it possible to efficiently learn images having different identities. In learning and recognition using a hierarchical network, it is known that, based on experiences, a layer near the input functions as a feature extractor for extracting a feature that is necessary for recognition, and a layer near the output performs recognition by combining extracted features. Thus, performing learning by setting a higher learning rate to a layer near the input side of the hierarchical network than a learning rate in a layer near the output side in second learning processing as in an aspect of the present invention corresponds to mainly relearning (adjusting) a feature extraction portion in data sets having different identities. Accordingly, the difference between data sets can be absorbed, and learning can be performed more efficiently than in the case of simply performing transfer learning.

  • Publication number: 20210076917
    Abstract: In an image processing apparatus according to a first aspect of the present invention, a first image is continuously acquired and displayed as a moving image by using first observation light until a still image acquisition instruction is received. When the still image acquisition instruction is received, a first image and a second image are acquired as still images by using first observation light and second observation light. After the still images have been acquired, a first image is acquired and displayed as a moving image again by using first observation light. Thus, the user is able to acquire still images by using first observation light and second observation light as necessary (for example, in response to a user instruction, or at a timing when acquisition of a still image is necessary such as when a region of interest is detected) while continuing observation with the first image, and is able to observe and classify a photographic subject.
