Group photographs are continuously taken with the same background, whereby at least two image frames are produced. A position of a face of each person is detected from each image frame. A combination weighting function w[p](x, y) is set such that, on the basis of the face detected in one of the two image frames, combination weights of pixels of the said one image frame to corresponding pixels of the other image frame are set, which combination weights decrease with increasing distance from the face of the person in said one image frame. The pixels of the said one image frame are laid on the corresponding pixels of the other image frame based on the combination weighting function w[p](x, y), whereby one composed image is produced.

Due to the great difference between an internal combustion engine vehicle (ICEV) and a new energy vehicle (mainly including a plug-in electric vehicle (PEV) and a hybrid electric vehicle (HEV)) in emission, a traditional environmental impact assessment method is challenging. According to the method, an absorption Markov chain model is used for modeling the transfer process between main vehicle types in the future. In addition, it is assumed that the behavior of a new energy automobile traveler is the same as that of a traditional ICEV traveler. Therefore, the vehicle composition of each road section is consistent with the market penetration level. Therefore, environmental impact assessment can be performed based on the market penetration levels of different vehicle types and the road traffic flow. For a given road network, traffic system equalization is utilized to calculate road segment traffic flow. The method is a four-stage model with feedback, and can be effectively solved througha weight decreasing continuous average method (MSA). The effectiveness of the proposed method is verified by using the simulation research of the Nguyen-Dupuis network.
