Abstract: An image processing system includes one or more processors comprising hardware configured to sequentially acquire time-series images captured by an endoscope, a dispose an evaluation mesh including a plurality of analysis points in a freely-selected timing image out of the time-series images, deform the evaluation mesh in each image of the time-series images so that each analysis point in each image of the time-series images tracks a characteristic point of an object located on each analysis point in the freely-selected timing image in which the evaluation mesh is disposed, calculate a deformation quantity of each cell of the evaluation mesh based on magnitude and a direction of a movement quantity of each analysis point in each image, and present information regarding deformation of the evaluation mesh based on the calculated deformation quantity.

Abstract: A medical system includes a treatment tool provided with an end effector that treats a tissue, an imager capturing an image of the tissue, and a processor. The processor acquires color information of a target tissue from the captured image output from the imager. The target tissue is a portion of the tissue that covers at least a portion of the end effector that has slid into the tissue. The processor estimates a force applied to the target tissue by the end effector from the color information of the target tissue. The processor notifies an operator of a result of the estimation of the force.
