This paper investigates the practical application of a new method called self-similar convolution masks to binary trademark images to produce affine invariant one dimensional histogram descriptions. Because the convolution mask is a scaled version of the original image, the normalised distribution histogram of the resulting grey scale image is an affine description based purely upon the image structure, which can be then be used for database search using a database of binary images. The effectiveness of this approach to trademark image identification is tested. Multiple methods of representing the distribution histograms within the database are also tested for robustness to noise, generalisation and reliability.
