A New Image Descriptor for Image Retrieval
نویسندگان
چکیده
Development of various image descriptors has greatly contributed to the advancement in image retrieval. Image descriptors can be made invariant to various image changes. In this paper, a new image descriptor is described and its application in image retrieval is evaluated. The descriptor uses the autoencoder concept to reduce the dimension of the feature vector measuing various properties of a keypoint. The new descriptor is found to have higher precision and recall rates when compared to the SIFT descriptor in image retrieval. Moreover, the descriptor is about three times faster than the SIFT descriptor, and by using the codebook concept, it can be made even faster.

New Pseudo-CT Generation Approach from Magnetic Resonance Imaging using a Local Texture Descriptor
Background: One of the challenges of PET/MRI combined systems is to derive an attenuation map to correct the PET image. For that, the pseudo-CT image could be used to correct the attenuation. Until now, most existing scientific researches construct this pseudo-CT image using the registration techniques. However, these techniques suffer from the local minima of the non-rigid deformation energy f...
