Figure Legend:
Power spectral analysis. (a) A sample outdoor template, which averaged the power spectra of all outdoor images in the data set (excluding the image itself if it is outdoor). (b) A sample indoor template, which averaged the power spectra of all indoor images in the data set (excluding the image itself if it is indoor). (c) Distribution of the ratio score for outdoor and indoor images. The ratio score of correlation coefficients is obtained from the outdoor correlation coefficient and indoor correlation coefficient for each image. Panel d shows two ROC curves (training and testing) of the classification results based on the correlation ratios. A weak classification result of 68.0% is achieved for separating indoor images from outdoor ones based on the average power spectra in the testing case.
