If you use the simple factory mode to create a cluster, you can easily determine the switch branch, and then assign different keys to the cluster directly. The cluster can be cached and initialized only once.

) Scale space search for predictive depth information : Most visual inspection methods, such as hog, use the search in the image scale space to discover the target. In the Hod method, you can use the depth information to guide this search process . With in-depth information for predictive assistance, search is more efficient and accurate .Our idea of improving the search process is to propose a method for quickly judging the corresponding scale of each position in the depth map. First, the avera

the Complie () conversion is used, the conversion is not performed at each match, and the matching efficiency is improved.The Re.search () method can be used as a matchobject or none, and therefore as a conditional statement. Re,match () will match at the beginning of the string, returning Matchobject or none.Case:# use Re.split () to divide the word some_text = ' alpha, beta,,,, Gama Delta ' re.split (R ' [,]+ ', Some_text) #结果为: [' alpha ', ' beta ', ' gama ', ' Delta ']# Re.findall () return
