This paper presents an atlas-based segmentation method for subcortical structures in magnetic resonance brain images. This method utilizes our previously introduced two-step registration comprising an affine transformation applied to the entire brain area followed by a local nonrigid transformation applied to subcortical structures. This method is compared(More)
3D imaging modalities are becoming increasingly popular and relevant in retinal imaging owing to their effectiveness in highlighting structures in sub-retinal layers. OCT is one such modality which has great importance in the context of analysis of cystoid structures in subretinal layers. Signal to noise ratio(SNR) of the images obtained from OCT is less(More)
