Designing hypothesis tests for digital image matching
Image matching in its simplest form is a two class decision problem. Based on the evidence in two sensed images, a matching procedure must decide whether they represent two views of the same scene, or views of two different scens. Previous solutions to this problem were either based on an intuitive …

Optical Three-Dimensional Image Matching Using Holographic Information
We present a three-dimensional (3-D) optical image matching technique and location extraction techniques of matched 3-D objects for optical pattern recognition. We first describe the 3-D matching technique based on two-pupil optical heterodyne scanning. A hologram of the 3-D reference object is …

Image matching and image super-resolution via deep learning
… alternative to traditional CAD-based and image-based approaches for 3D modeling. The output of the 3D depth sensors is generally 3D color point cloud and LIDAR images which is collected at the time of the LIDAR survey. However, in order to model 3D scenes under different conditions …

Spectral control of viscous alignment for deformation invariant image matching
… present a new approach to deformation invariant image matching. Our approach retains the broad range of linear and nonlinear deformations that viscous alignment methods can model, but introduces a selectivity that is necessary for recognition. Our method models viscous kernels with an …

Development of an image matching scheme using feature- and area based matching techniques
Image matching is widely considered to be one of the most difficult tasks of a digital photogrammetric system. Traditionally image matching has been approached from either an area based or a feature based point of view. In recent years significant progress has been made in Area Based Matching (ABM) …

Development and application of a non invasive image matching method to study spine biomechanics
… such as magnetic resonance and fluoroscope images, which are widely accessible nowadays, have the potential to study in-vivo spine biomechanics accurately and non-invasively. This research presents a new combined magnetic resonance and fluoroscope imaging matching method to study human …

Test and evaluation of an image-matching navigation system for a UAS operating in a GPS-denied environment
… in sensor resolution. The concept of using an image-matching technique on an input video camera stream was demonstrated earlier with real flight data using a single low-grade onboard sensor. This technique works by matching the stream of data from the camera with a pre-stored depository of …

Technique and application of a non-invasive three dimensional image matching method for the study of total shoulder arthroplasty
… a non-invasive three dimensional fluoroscopic image matching method was developed and validated for use in the shoulder joint complex. Next, a group of patients that have undergone clinically successful total shoulder arthroplasty surgeries were recruited for study and imaged by the …

An investigation into the design of a satellite based stereo imaging sensor and the use of automatic image matching in the production of digital elevation models
… based stereo imaging sensor and the automatic matching of digital stereo images for automatic cartography applications. The two problems are related; they are both components of a stereo vision system. The research was initially motivated by the decision of the Department of Electrical and …

Analysis of photogrammetrically-derived digital surface and terrain models for building recognition
… is structured into four main parts, namely, image matching to derive the data sets, building detection to delineate buildings from other man-made objects in DSM (digital surface model), DSM quality analysis to determine the reliability of the data, hydrological analysis to determine flood …

Object reconstruction using close-range all-round digital photogrammetry for applications in industry
… of photogrammetry. To obtain the necessary imagery from all sides of the measurement object, real-time processing is nearly impossible, and it becomes difficult to avoid moving the object, thus precluding in situ measurement. However, all-round digital photogrammetry and, in particular, the …

Search-based Automatic Image Annotation Using Geotagged Community Photos
… for sharing and collaboratively annotating images with keywords, called tags, became very popular. Tags are a powerful means for organizing and retrieving photos. However, manual tagging is time consuming. Recently, the sheer amount of user-tagged photos available on the Web encouraged …

Pattern recognition and the nondeterminable affine parameter problem
… a number of pattern recognition systems for two image recognition problems that occur in the field of image matching have been developed. These image recognition problems and the issues involved in solving them are described in detail. Numerous experiments were carried out to test the accuracy …
