Given your image im, you can binarize it with im2bw:
bw = 1-im2bw(image);
The horizontal histogram (I guess) is the sum of the object in the horizontal direction, which is
h = sum(bw,2)
You can then plot it with:
figure
plot(sum(bw,2),1:size(bw,1))
Which gives you the image attached.
The segmentation could be performed with findpeaks.

Threshold it and then use regionprops(labeledImage, 'PixelIdxList') to find where each line starts and stops (what row indexes), or what rows have text in them.
