Use regionprops(), and ismember():
labeledImage = bwlabel(binaryImage);
props = regionprops(labeledImage, 'BoundingBox');
bb = vertcat([props.BoundingBox]);
% See if column width > height
widths = bb(:, 3);
heights = bb(:, 4);
goodLabelsIndexes = find(widths <= heights); % And discard if widths > heights
% Remove bad blobs
binaryImage = ismember(labeledImage, goodLabelsIndexes);
% Mask the image using bsxfun() function to multiply the mask by each channel individually.
maskedRgbImage = bsxfun(@times, rgbImage, cast(binaryImage, 'like', rgbImage));
