A Collective Sense of Place and the Image of the City @ Urban Public Spaces: Analysis on People's Perception of User-Generated Image Content and Hashtags on Instagram
… and exchange various forms of User-Generated Content (UGC) has gained wide attention as an invaluable source of information on human-environment relationships including people's timely perception, emotion, preference, and sense of place in public space. This study employs quantitative content …

A framework for automated landmark recognition in community contributed image corpora
… efficiently and collections of digital images are no exception. Automatically creating high-level semantic tags based on image content is difficult, if not impossible to achieve accurately. In this thesis a framework is presented that allows for the automatic creation of rich and …

Recognition of 3D compressed images and its traffic monitoring applications
… These systems must manage large numbers of images sent over communication networks. For example, a high transmission load results when security cameras continuously transmit images. Operators are bored and fatigued from viewing cycled images on a few monitors. In this thesis, we present a …

Accelerating Physically-Based Light Transport Algorithms
… sampling strategies which adapt themselves to image content in an unbiased manner. We demonstrate that these techniques offer substantial improvement over the prior art and offer sufficient generality to be deployed in many path tracing-based light transport algorithms.

Content-prioritised video coding for British Sign Language communication.
… media applications which must compress video image data for efficient transmission. Current video compression schemes apply methods to reduce statistical redundancy and perceptual irrelevance in video image data based on a general model of Human Visual System (HVS) sensitivities. This thesis …

Registration of images containing rigid structures using deformable models and its medical application
… research and development in registration of images containing rigid structures using deformable models. In the existing methods of deformable image registration, the feature based methods using purely interpolation are often used under the assumption that all parts of the image can be …

Classification of Carpiodes Using Fourier Descriptors: A Content Based Image Retrieval Approach
… The current state of computer technology makes image storage and retrieval possible on a global level. As a result, computer-aided taxonomy is now possible. Content based image retrieval techniques utilize visual features of the image for classification. By utilizing image content and computer …

Image Quality Analysis Using GLCM
… help understand the details about the overall image content. The aim of this research is to investigate the use of the gray level co-occurrence matrix technique as an absolute image quality metric. The underlying hypothesis is that image quality can be determined by a comparative process in …

Photo engagement: how presentation and content of images impact their engagement and diffusion
… social media channels has shifted from text content to include an increasingly large number of images. Visual traces resulting from people's online social behavior have the potential to reveal insights about our habits, activities and preferences. The role of social network-related factors …

Implicit Concept-based Image Indexing and Retrieval for Visual Information Systems
This thesis focuses on Implicit Concept-based Image Indexing and Retrieval (ICIIR), and the development of a novel method for the indexing and retrieval of images. Image indexing and retrieval using a concept-based approach involves extraction, modelling and indexing of image content information. …

Connected operators for unsupervised image segmentation
Image segmentation forms the first stage in many image analysis procedures including image sequence re-timing and the emerging field of content based retrieval. By dividing the image into a set of disjoint connected regions, each of which is homogeneous with respect to some measure of the image …

Methods for recognizing patterns in digitized line drawings
… As a means for the automatic analysis of picture content, a model based recognizer for line patterns is developed. The pattern matcher uses a simple scheme to decompose a line drawing into basic parts: strokes and junctions, and then finds graph isomorphisms between known line pattern models …

StreetScenes : towards scene understanding in still images
… understanding system that is able to analyze the content of real images. While constructing the system we had to provide solutions to many of the fundamental questions that every student of object recognition deals with daily. These include the choice of data set, the choice of success …
