Compressing a logical array into a bit-wise boolean representation
显示 更早的评论
Standard MATLAB logical arrays use 1 byte to represent each boolean element in the array. However, I seem to remember coming across a way, maybe in the Image Processing Toolbox, to convert a logical array to a representation that uses only 1 bit per boolean. My recollection is fuzzy, but can anyone recognize what I'm referring to and, if so, point me to the appropriate doc?

may be bwpack is function you are looking.
from help.
BWP = bwpack(BW) packs the uint8 binary image BW into the uint32 array BWP, which is known as a packed binary image. Because each 8-bit pixel value in the binary image has only two possible values, 1 and 0, bwpack can map each pixel to a single bit in the packed output image.
