1. A method for automatically inspecting railroad tracks comprising:

  • assessing a configuration of rail components depicted in an image by comparing the configuration of the rail components to safety requirements for the rail components;

    dividing the image into a set of cells;

    extracting texture features from each cell from the set of cells;

    grouping the set of cells into classes based on the texture features from each cell;

    binarizing the image based on class grouping of the texture features from each cell; and

    determining a severity of detected problems in the configuration of the rail components, using a computer processor.
