Localized texture analysis of breast tissue on mammograms is an issue of major importance in mass characterization. This material aims to the establishment of a quantitative approach of mammographic masses texture classification based on these datasets of the extracted textural features.
This package contains an extensive set of textural feature datasets, in multiple configurations and scales, constructing compact sets of textural "signatures" for benign and malignant cases of tumors in mammograms. The datasets refer to 142 localized masses in mammograms, as well as a set of qualitative features that have been proven as of utmost importance regarding the true pathology in each case. For the construction of the raw material for these datasets, 130 of the 142 MLO mammograms containing a mass were selected by an expert physician for digitization, including a total of 46 benign mass cases and 84 mass malignancies of various types (12 were marked 'unreliable').
The files also include the full texture data of 7,000-13,000 sampling "boxes" of sizes 20 and 50 pixels, as well as complete-mass and borderline-only sampling areas.
The digitized mammograms were subsequently transformed digitally to a resolution of 63 mm (400 dpi) at 8-bit gray level, which is consistent with other typical image databases of digitized mammograms that are used as a reference in similar studies.
Detailed information about the files and the structure of the datasets are available in the manifest file (S2_data_texture_directory.pdf).
