python处理.seq文件
# Deal with .seq format for video sequence # Author: Kaij # The .seq file is combined with images, # so I split the file into several images with the image prefix # "\xFF\xD8\xFF\xE0\x00\x10\x4A\x46\x49\x46". import os.path import fnmatch import shutil def open_save(file,savepath): # read .seq file, and save the images into the savepath f = open(file,'rb') string = str(f.read()) splitstring = "\xFF\xD8\xFF\xE0\x00\x10\x4A\x46\x49\x46" # split .seq file into segment with the image prefix strlist=string.split(splitstring) f.close() count = 0 # delete the image folder path if it exists if os.path.exists(savepath): shutil.rmtree(savepath) # create the image folder path if not os.path.exists(savepath): os.mkdir(savepath) # deal with file segment, every segment is an image except the first one for img in strlist: filename = str(count)+'.jpg' filenamewithpath=os.path.join(savepath, filename) # abandon the first one, which is filled with .seq header if count > 0: i=open(filenamewithpath,'wb+') i.write(splitstring) i.write(img) i.close() count += 1 if __name__=="__main__": rootdir = "D:\\Data\\feifei" # walk in the rootdir, take down the .seq filename and filepath for parent, dirnames, filenames in os.walk(rootdir): for filename in filenames: # check .seq file with suffix if fnmatch.fnmatch(filename,'*.seq'): # take down the filename with path of .seq file thefilename = os.path.join(parent, filename) # create the image folder by combining .seq file path with .seq filename thesavepath = parent+'\\'+filename.split('.')[0] print "Filename=" + thefilename print "Savepath=" + thesavepath open_save(thefilename,thesavepath)
先贴出代码,最近做实验要用到加州理工的行人数据库,下载一看,是把图像按照二进制数据形式存储为.seq文件,没办法,找到一个哥们写的用python处理seq文件,将数据转换为.jpg图像。代码直接可用,只需要把文件搜索目录“rootdir”改为你自己文件的目录就OK了
