Abstract
Clinical images are of utmost importance for the majority of dermatological research and publications. The rich collection of clinical images in medical journals may help in formulating machine learning programs in the future or facilitate image-based meta-analysis. However, the presence of a scale bar in those images is required for measuring the lesion from an image. We audited recent issues of three widely circulated Indian dermatology journals and found that among 345 clinical images, 2.61% had a scale with the unit. With this background, in this article, we provided three methods for capturing and processing clinical images with scale. This article would help dermatologists to think about incorporating a scale bar in the image for the progress of science.
