Adaptive-weighted bilateral filtering and other pre-processing techniques for optical coherence tomography ?
An integrated image processing toolbox for retinal image analysis is proposed. The system considers in a unified framework both fundal images and optical coherence tomography. An adaptive-weighted bilateral filtering (AWBF) is proposed to reduce speckles. The dual-tree complex wavelet transform is employed to improved OCT layer segmentation. A novel technique for multimodal retinal image registration is proposed.
