1. An apparatus for evaluating a tissue image for a medical condition, the apparatus comprising:
- a model predictive of the medical condition, wherein the model is based on one or more fractal dimension features from one or more binary images, each binary image corresponding to a particular color channel of the tissue image, said model defining a relationship between the expression of said one or more fractal dimension features and the medical condition, wherein the model is configured to;
receive data identifying an expression of said one or more fractal dimension features within the tissue image; and
evaluate said data according to the relationship defined by the model to produce a value indicative of at least one of the presence, absence, or aggressiveness of the medical condition.

Abstract
Systems and methods are provided for automated diagnosis and grading of tissue images based on morphometric data extracted from the images by a computer. The morphometric data may include image-level morphometric data such as fractal dimension data, fractal code data, wavelet data, and/or color channel histogram data. The morphometric data may also include object-level morphometric data such as color, structural, and/or textural properties of segmented image objects (e.g., stroma, nuclei, red blood cells, etc.).
