Our aim was to investigate the registration and fusion of models reconstructed from multimodal craniocerebral sectional images, providing basis of craniocerebral structure visualization for surgical navigation. The craniocerebral dataset from different modalities were obtained and constructed. For segmentation, “training area” and “threshold” methods were performed for white matter in MRI coronary...
A new image transform, namely, the quad-tree complex wavelet packets transform (QCWPT) is introduced ,which both has shift invariance and good direction analysis ability and other merits of the dual-tree complex wavelet transform (DCWT), and has the ability of analyzing the high frequency detail signal carefully like the wavelet packet transform (WPT). Furthermore, a novel image denoising scheme based...
