Description	This paper deals with the comparison of information content of interest points in images detected with different blob detectors. Specifically, the Hessian, Hessian-Laplace, Fast Hessian and Difference of Gaussian detectors are compared. We have performed the measurement on five image collections each containing images of one category. The tested categories are namely: houses, cars, nature, portraits and interior images. Each collection contains one hundred greyscale images. We have compared the information content of the interest points and randomly selected points and observed that the interest points convey more information than the randomly distributed points. The Fast Hessian detector and Difference of Gaussians detector perform best and entropy of points detected by these algorithms reaches 5 Shannons.
