Abstract: A learning input image is input to a first sub-model to extract a first feature map, and a first output image is output based on the first feature map. The first feature map is input to a second sub-model to extract a second feature map, and a second output image having a higher resolution than the first output image is output. In response to an inference input image being input to a trained learned model, the first output image as an inference result image is output.

Abstract: In a medical image processing apparatus including a processor, the processor sequentially acquires time-series medical images and causes a display unit to sequentially display the acquired medical images. Further, the processor performs a process of acquiring, based on the acquired medical images, information related to a position of a region of interest in the medical images and classifying the region of interest into a class among a plurality of classes, and displays class information indicating the class of the classified region of interest such that the class information is superimposed at a position of the region of interest in a medical image displayed on the display unit. Further, the processor changes a relative position of the superimposed class information with respect to the region of interest, in accordance with an elapsed time from recognition of the region of interest.

Abstract: An input receiving unit receives a designation input of a user for a medical image displayed on a first display screen of a display. An image selection unit acquires selected images selected from a plurality of medical images based on a designated image category that is a category assigned to a designated image and a non-designated image category that is a category assigned to a non-designated image. The selected images are displayed in a list on a second display screen of the display.

Abstract: A trained first model is generated through first learning using a first learning image group constituted of a normal image which is a medical image having no region of interest. An input image group including at least the medical image different from the first learning image group is input to the trained first model, and abnormality detection is performed. The extracted image used for learning to prevent erroneous recognition is sorted according to a result of the abnormality detection, and second learning using a second learning image group including at least the extracted image is performed. A second model that detects the region of interest is generated through the second learning.

Abstract: Provided are a medical image processing apparatus and a medical image processing method that effectively display an observation state indication related to the comprehensiveness of observation while suppressing a decrease in the visibility of an endoscopic image. The medical image processing apparatus is a medical image processing apparatus including a processor and a memory. The processor is configured to acquire a plurality of medical images in a time-series manner, make a determination of an observation state in units of a small area of a photographic subject on the basis of the medical images, cause the memory to store a result of the determination, and upon an observation state of the photographic subject being changed, cause a monitor to display an observation state indication of the photographic subject, the observation state indication being based on the result of the determination stored in the memory.

Abstract: A medical image processing apparatus includes a recognition unit that detects a region of interest from an acquired medical image and classifies the region of interest; a display control unit that causes emphasis display for emphasizing the region of interest and a classification for the region of interest to be displayed in a screen identical to a screen for displaying an observation target included in the medical image; and an observation image switching unit that switches whether to display consecutive images or to display a still image by using a display device. In a case where consecutive image display of an observation image is switched to still image display by the observation image switching unit, the display control unit makes a change for reducing visual recognizability of at least any of the emphasis display or the classification compared with a case of the consecutive image display of the observation image.

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.

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.
