Rescalling of depth map

[Astrosun]

Hi,

I have prepared my data set which contains RGBD 4 channels. I find that the depth image is of uint16 type which leads to that pixel value range in my depth image is from 1 to 2^16 which is different from the range of RGB channel (uint8) which is from 1 to 2^8.

I rescale the depth image range from( 1 to 2^16) to (1 to 2^8) by using matlab function "im2uint8" to make sure that all the 4 channels are in the same scale.

Just want to double check that whether this is the correct way to deal with it?

Thanks!
