Image database retrieval with multiple-instance learning techniques
… we develop and test an approach to retrieving images from an image database based on content similarity. First, each picture is divided into many overlapping regions. For each region, the sub-picture is filtered and converted into a feature vector. In this way, each picture is represented by a …

The use of images and descriptive words for the development of an image database for product designers
This research aims to understand the role images currently play within the design process, in order to develop a classification of image types and reference keywords to construct an electronic image database for professional use in product design. Images play an important role in the design …

Human performance evaluations of selected image enhancement/restoration techniques
… research program designed to establish a digital image database, to standardize a set of experimental procedures of obtaining human performance data, and to relate these performance measures to various image display conditions. The image database consists of low-altitude aerial scenes of various …

Efficient object recognition and image retrieval for large-scale applications
… In many real-world systems, large numbers of images are constantly added to the database, requiring the algorithm to quickly tune itself to recent trends so it can serve queries more effectively. Moreover, the systems need to be able to meet the demands of simultaneous queries from many users. …

Learning and applying model-based visual context
… of learning visual context models from an image database, I demonstrate the utility of the model-based approach. The system is capable of learning models for "water-horizon scenes" and "suburban street scenes" from a database of 745 images.

Modeling image databases using Xml schema
This thesis presents a model for still images in order to support content-based querying and browsing by hierarchical tree structures and object relational graphs. We use the extensible markup language (XML) schema to illustrate and exemplify the proposed model because of its interoperability and …

It may be Architecture
Architecture’s relationship to images is manifold: architecture starts with an image and results in an image. Staying true to the claim, the thesis posits that architecture and its images are interchangeable and enforces that the image should be translated into a spatial condition. The aim is to …

Measuring and modifying the intrinsic memorability of images
… a procedure to measure the memorability of an image by running hundreds of human-trials and making use of a custom designed image dataset, the Mem60k dataset. The large store of ground-truth memorability data enabled a variety of insights and applications. The data revealed information about …

Exploring Cranial Macromorphoscopics from Adult Computed Tomography Scans Using an Anatomage Table
… for viewing 3D renderings of digitized images in biological anthropology. This project uses an Anatomage Table to produce 3D renderings of computed tomography scans obtained from the New Mexico Decedent Image Database (NMDID) to test the virtual MMS trait collection protocol.

Skew estimation for document images
… a series of skew estimation models for document images, which include the fiducial-line based which relies on the existence of text lines, the convex-hull based which relies on the existence of paragraphs or columns, and the straight-edge based which relies on the existence of non-textual …

Content-based indexing of low resolution documents
… devices is gaining popularity. To enhance the image usefulness, the images captured could be linked to image or video database. The database can be used for the purpose of file archiving, teaching and learning, research and knowledge management, which concern image search. However, the …

Detecting domestic objects with ensembles of view-tuned support vector machine cascades trained on Web images
This thesis develops a system, based on Web images, for the detection of domestic objects in images of indoor home environments. Images from ten different domestic object categories (apple, bottle, bowl, cup, handbag, laptop, light switch, potted plant, shoe and toaster) are downloaded and …

Tissue spectroscopic characterization based on fluorescence, second harmonic generation, and reflected light
… structure of a tissue specimen with an image database containing known physiological and pathological tissue structures. Three new microscopy technologies are developed to complement histology based on novel contrast mechanisms to better visualize and understand tissue structure and …

DATA MINING TECHNIQUES ON VOLCANO MONITORING
… signals and another to index an thermal image database are presented.

Labeling, discovering, and detecting objects in images
… few of these factors: the importance of labeled image databases for recognition, the ability to discover object categories from simply looking at many images, and the use of large labeled image databases to efficiently detect objects embedded in scenes. For each of the issues above, we will need …

City-scale Cross-view Geolocalization with Generalization to Unseen Environments
… global position by matching a local ground image to an overhead satellite image. It is challenging to reliably match these two sets of images in part because they have significantly different viewpoints. Existing works have demonstrated geolocalization in constrained scenarios over small …

A Methodology for the Development of a Production Experience Database for Earthmoving Operations Using Automated Data Collection
… on operating conditions is facilitated by image database and paper forms. The cycle time data and the information on operating conditions are linked together to form the experience database. This research developed methods to extract, quantify and understand the variation in each component …

Data-driven photographic style using local transfer
… using built-in applications to adjust the image's luminance, coloring, and details. In general, photographers who stylize pictures give them new, different visual appearances, while also preserving the original content. In this context, we investigate problems with novel image stylization, …
