We describe a method for reducing the width of panoramic images with high aspect ratios on the basis of the entropy in local color histograms computed for each column in the images. We equalize the entropy for the width of a panoramic image, thereby widening the regions that have high entropy values and narrowing the regions that have low entropy values. Our experimental results show that this method can reduce the width of panoramic images more effectively and more quickly than the seam carving method presented by Avidan et al.
