some question

[zxfever]

Hello
I have solved some questions when i run the code with grayscale image in the 00 sequence，but i have a new error as follow，it occurred while reading the 455th images

OpenCV Error: Image step is wrong (The matrix is not continuous, thus its number of rows can not be changed) in reshape, file /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/core/src/matrix.cpp, line 1102 terminate called after throwing an instance of 'cv::Exception'

could you give me some advice?Thanks a lot!
