2results about How to "Reduce split" patented technology

The application relates to a sea fog monitoring method and device, electronic equipment, a storage medium and a product. The method comprises the following steps: acquiring image data of a target region to be identified; inputting the image data into a classifier to obtain a sea fog identification candidate result; determining a sea fog core pixel and a sea fog determination rule based on the sea fog identification candidate result; taking the sea fog core pixel as a starting point, judging whether adjacent pixels satisfy the sea fog determination rule one by one until all the pixels in the image data are traversed, and obtaining a sea fog identification target result. In this way, the classifier is used to quickly narrow the candidate range, and then the key region is focused for growth verification, so that the calculation efficiency and the identification accuracy are considered, invalid calculation is reduced, the local deviation of the classifier is compensated, and the problem that a single sub-growth is easily disturbed by noise is solved; the pixel-by-pixel verification of the core pixel not only naturally matches the continuous distribution characteristics of the sea fog, reduces the complete fog area from being split, but also can accurately depict a gradual edge and match the real shape of the fog area.

The application relates to a carbon material, a preparation method thereof, a negative electrode material and a battery. The carbon material has a rod-like structure, has pores and has a length-diameter ratio of 3-15. The carbon material has a rod-like structure, can reduce inter-particle pores, reduce particle breakage during pressing of an electrode sheet, and is beneficial to improving the compaction density, the energy density and the electrochemical performance of the material.
