    摘要: A method and a system for traffic light detection are provided. The method may include: obtaining a color image; calculating pixel response values for pixels of the color image, respectively, where each of the pixel response values may be calculated using R, G, and B values of a corresponding pixel directly, such that pixel response values of red traffic light pixels are substantially distributed on a first side of a predetermined range and pixel response values of green traffic light pixels are substantially distributed on a second side of the predetermined range which is opposite to the first side; identifying pixels whose pixel response values are distributed on the first side or the second side as candidate pixels; identifying candidate blobs based on the candidate pixels; and verifying whether the candidate blobs are traffic lights. Efficiency and reliability may be improved.

    摘要: Disclosed are a flexible polymer, particles made from same, and a process for preparing the particles. This flexible polymer is obtained from copolymerizing monomer (A) and monomer (B), wherein monomer (A) is one or more water-insoluble unsaturated diene monomers; monomer (B) is at least one compound with the general formula of wherein R is C1-C12alkyl, C1-C12 alkyl aryl, C1-C12 alkyl ether or C1-C12alkyl ester. Monomer (A) is in an amount of 60-90% by weight of the total combined weight of monomer (A) and monomer (B). Monomer (B) is in an amount of 10-40% by weight of the total combined weight of monomer (A) and monomer (B). The flexible polymer particles show excellent flexibility, deformability, elasticity as well as stability. They can be used in oilfields in nearby wellbore profile control and in-depth profile control or as in-depth flooding fluid diverting agents. They can also be applied in water shutoff in high temperature and high salinity production wells; preventing chemical channeling in polymer and ASP (alkali-surfactant-polymer) flooding; temporarily plugging in acidization; huff and puff; and preventing in-depth channeling in steam flooding, loss of circulation control and filtration control, and the like.

    摘要: A method for detecting traffic lights is provided. The method includes: obtaining a color image captured by a camera; converting the color image into a first monochrome scale image; converting the first monochrome scale image into a first binary image; identifying a first set of candidate blobs in the first binary image based on at least one predetermined geometric parameter; and determine whether a first region in the color image, which first region corresponds to one of the first set of candidate blobs, is a green traffic light using a green traffic light classifier. The accuracy and efficiency may be improved.
