Spines are protrusions of neuronal dendritic surfaces. These subcellular compartments are essential in neuronal information processing since electrical signals from other neurons are transmitted to dendrites via synaptic gateways located at dendritic spines. One of the important tasks for assessing synaptic strength is estimating the volume of spines, which is quite challenging because the image resolution for spines in live animal microscopy images is low and the level of noise is high. In order to carry out this task we develop a method for spine surface segmentation using sparse representations based on directional 3D filters with small spatial support.
