An open-access computer image analysis (CIA) method to predict meat and fat content from an android smartphone-derived picture of the bovine 5th-6th rib

•A smartphone image was captured under very few fixed conditions.•Seventeen image features were semiautomatically produced in less than 5 min.•High correlations existed between the lipid content (IMF) and fat fleck area.•High correlations existed between lean or fat weight and intermuscular fat area.•Accurate predictions of IMF and rib composition were obtained from image features.
