puzzled on color conversion #31

Closed hengliusky closed 7 years ago

hengliusky commented 7 years ago

In some prototxt files, the layer "ColorConv" is used to deal with rgb->lab. But in other prototxt files, the python code "color.rgb2lab" take the place. why do not use the same way? In addition, the layer ColorConv" can not be found in normal Caffe version. what the data type (0-1,or 0-255) should be used when adopting ColorConv?
