matlab 相关代码记录

1. 判断是否存在指定的video_name, 若不存在,则在给定save_path下,新建一个video_name文件夹:

1 sec_path = [save_path, video_name, '/']; 2 if ~exist(sec_path,'file') 3 mkdir([save_path, video_name]); 4 end

2. 将gpuArray转换为matlab可以保存的格式,如:uint8 等。
if you save the gpuArray data directly, it will warning you some errors like this:


and translate it into numeric or logical is necessary...

    % gpuArray to matlab format, person_image is the gpuArray and first translate it into
single format using "gather" function which is the matlab inside function.

    person_image = im2uint8(gather(person_image));
