Global Patch Matching (GPM) for freehand 3D ultrasound reconstruction
BACKGROUND 3D ultrasound volume reconstruction from B-model ultrasound slices can provide more clearly and intuitive structure of tissue and lesion for the clinician. METHODS This paper proposes a novel Global Path Matching method for the 3D reconstruction of freehand ultrasound images. The proposed method composes of two main steps: bin-filling scheme and hole-filling strategy. For the bin-f...
متن کاملMixed-Resolution Patch-Matching
Matching patches of a source image with patches of itself or a target image is a first step for many operations. Finding the optimum nearest-neighbors of each patch using a global search of the image is expensive. Optimality is often sacrificed for speed as a result. We present the Mixed-Resolution Patch-Matching (MRPM) algorithm that uses a pyramid representation to perform fast global search....
متن کاملPredictive Patch Matching for Inter Frame Coding
Inter prediction is an important component for video coding which exploits the temporal correlation between frames and significantly reduces the redundancy in video sequences. In this paper, we propose a predictive patch matching for inter prediction based on template matching prediction. Besides the surrounding reconstructed pixels which form the template in template matching prediction, our p...
متن کاملA Large Dataset for Improving Patch Matching
We propose a new dataset for learning local image descriptors which can be used for significantly improved patch matching. Our proposed dataset consists of an order of magnitude more number of scenes, images, and positive and negative correspondences compared to the currently available Multi-View Stereo (MVS) dataset from Brown et al. [1]. The new dataset also has better coverage of the overall...
متن کاملGeometic Constraints from Planar Surface Patch Matching
Some three dimensional scene analysis programs pair data surface patches (i.e. as extracted from range data) to model surface patch features. From the correspondences, a variety of rotation and translation constraints of the model can be deduced, depending on the assumptions behind the correspondences. This paper elaborates some of the constraints available when single planar patches are relate...
