In this presentation we address the problem of user identification using ear biometrics in the context of sparse representation. During the training session the compressed ear images are transformed to vectors to develop a dictionary matrix. The downsampled probe vector is used to develop a linear, underdetermined system of equation. The inverse problem is solved through the l1-norm minimization. Ideally the nonzero entries in the recovered vector correspond to the class of the probe.
