Abstract: A laparoscopic image smoke removal method based on a generative adversarial network, and belongs to the technical field of computer vision. The method includes: processing a laparoscopic image sample to be processed using a smoke mask segmentation network to acquire a smoke mask image; inputting the laparoscopic image sample to be processed and the smoke mask image into a smoke removal network, and extracting features of the laparoscopic image sample to be processed using a multi-level smoke feature extractor to acquire a light smoke feature vector and a heavy smoke feature vector; and acquiring, according to the light smoke feature vector, the heavy smoke feature vector and the smoke mask image, a smoke-free laparoscopic image by filtering out smoke information and maintaining a laparoscopic image by using a mask shielding effect. The method has the technical effects of robustness and ability of being embedded into a laparoscopic device for use.

Abstract: A safety helmet in the form of a cycling helmet or similar. The helmet has an outer shell and an energy-absorbing liner within the outer shell. The energy-absorbing liner is provided by a cellular textile material combined with a matrix material to form a composite. The composite material retains some porosity from the original textile material to both improve breathing of the liner and also its capability for large deformations to improve energy absorption. The liner may also be provided with a linkage structure to link adjacent cells to improve the absorption of impact loads over a number of adjacent cells in the composite material.
