Error using bwlabel
Expected input number 1, BW, to be two-dimensional.

jpg files are almost always RGB images even if they look like black and white. You need to rgb2gray() the content and perhaps im2bw() the result.

You call it BW but it's most likely not a binary image. It's probably gray scale or color. You need to binarize your grayscale image first. For example threshold it
grayImage = imread(filename);
BW = grayImage < 100;
