Automatic classification of colorectal and prostatic histologic tumor images using multiscale multispectral local binary pattern texture features and stacked generalization

•A grade diagnostic formulation is considered rather than a malignant versus benign tumour problem.•A new multispectral multiscale linear binary pattern feature is proposed.•Multispectral images acquired in the visible and infrared spectra are considered.•A stacked generalisation classification technique is proposed.
