Objective.
To investigate differences in tongue images of subjects with and without hyperuricemia.
Materials and Methods.
This population-based case-control study was performed in 2012-2013.
We collected data from 46 case subjects with hyperuricemia and 46 control subjects, including results of biochemical examinations and tongue images.
Symmetrical Haar-like features based on integral images were extracted from tongue images.
T-tests were performed to determine the ability of extracted features to distinguish between the case and control groups.
We first selected features using the common criterion P < 0.05 , then conducted further examination of feature characteristics and feature selection using means and standard deviations of distributions in the case and control groups.
Results.
A total of 115,683 features were selected using the criterion P < 0.05 .
The maximum area under the receiver operating characteristic curve (AUC) of these features was 0.877.
The sensitivity of the feature with the maximum AUC value was 0.800 and specificity was 0.826 when the Youden index was maximized.
Features that performed well were concentrated in the tongue root region.
Conclusions.
Symmetrical Haar-like features enabled discrimination of subjects with and without hyperuricemia in our sample.
The locations of these discriminative features were in agreement with the interpretation of tongue appearance in traditional Chinese and Western medicine.
