Video-LLaVA: Learning United Visual Representation by Alignment Before Projection
Conference on Empirical Methods in Natural Language Processing, 2023Large Vision-Language Model (LVLM) has enhanced the performance of various downstream tasks in visual-language understanding. Most existing approaches encode images and videos into separate feature spaces, which are then fed as inputs to large language ...

Automatic alignment of radionuclide images
Physics in Medicine & Biology, 1982The variability of the position, dimensions and orientation of a radionuclide image within the field of view of a gamma camera hampers attempts to analyse the image numerically. A method is described for using a set of training images of a particular type, in this case right lateral brain images, to define the likely variations in the position ...

SAR2OPT: Image Alignment Between Multi-Modal Images Using Generative Adversarial Networks
IEEE International Geoscience and Remote Sensing Symposium, 2019This work proposes an image-alignment method for multi-modal images (e.g., synthetic aperture radar (SAR) and optical satellite images) using an image-feature-based keypoint-matching algorithm.

Alignment of X-ray bone images
2014 X International Symposium on Telecommunications (BIHTEL), 2014Switching to digital technology from analog brought many changes, especially in storage of digital X-ray images. In cases of multiple fractures or need for imaging of a large area it is necessary to make more than one X-ray image for the observed part of body. This is often the case with spine, legs and arms.

Fast Fingerprint Image Alignment
2012Fingerprint is one of the various modalities used in biometrics for authentication. An important issue, when designing a fingerprint–based biometric system / application is alignment of fingerprint images before feature extraction and matching. In this paper we present fingerprint alignment algorithm based on Principal Component Analysis (PCA).

BiFA: Remote Sensing Image Change Detection With Bitemporal Feature Alignment
IEEE Transactions on Geoscience and Remote SensingDespite the success of deep learning-based change detection (CD) methods, their existing insufficiency in temporal (channel and spatial) and multiscale alignment has rendered them insufficient capability in mitigating external factors (illumination ...

Image Alignment-Based Multi-Region Matching for Object-Level Tampering Detection
IEEE Transactions on Information Forensics and Security, 2017Tampering detection methods based on image hashing have been widely studied with continuous advancements. However, most existing models cannot generate object-level tampering localization results, because the forensic hashes attached to the image lack ...
