Brough, Vivienne. "Affects of ekstasis in surrealism's occluded practices." Thesis, University of Essex, 2012. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.558815.

Abstract:

This study proposes that there exists a coherent alternative strand of surrealist praxis evident in works produced by certain international surrealists and ex-surrealists: this strand is seen to be marked by a presentation of the affects of ekstasis. This proposition is examined in relation to three differentiated international prose works. This spectrum of responses is charted through the novels, Zenobia (1985, En. ed. 1995) by the Romanian Gellu Naum, Le Cornet acoustique (The Hearing Trumpet) (1974, En. ed. 1976) by the British expatriate Leonora Carrington, and Los pasos perdidos (The Lost

Abstract:

The purpose of this research was to study children's ability to recognize partially occluded images. Tasks were constructed which consisted of occluded images from video games, trademarks, and household objects. The tasks were administered to third and sixth grade students at two elementary schools in Arlington, Texas. The researcher discovered no significant differences between the scores of males and females except for the males' higher score on the video game task .

Abstract:

<p>The aim of the thesis is object finding in occluded and cluttered environment using computer vision techniques and robot motion. Difficulties of the object finding are 1. finding objects at hidden area and 2. finding unrecognized objects. For solving the difficulties, two methods were developed, one is for finding objects in occluded cluttered environments using model based object finding and the other to increase the robustness in object finding by identifying known objects that are unidentified. The goal was to search occluded areas with the bumblebee2 stereo camera to be able to identify

Abstract:

This thesis develops an algorithm for approximate string matching and applies it to the problem of partially occluded object recognition. The algorithm measures the similarity of differing strings by scanning for matching substrings between strings. The length and number of matching substrings determines the amount of similarity. A classification algorithm is developed using the approximate string matching algorithm for the identification and classification of objects. A previously developed method of shape description is used for object representation.

Abstract:

<p>This thesis demonstrates that infants represent temporarily non-visible, or occluded, objects. From 4 months of age, infants could accurately predict the reappearance of a moving object after 660 ms of non visibility; indicating accurate spatiotemporal representations. At this age predictions were dominated by associations between specific events and outcomes (associative rules). Between 6 and 8 months of age predictions became dominated by extrapolations (Study III). From 6 months infants could represent occluded objects for up to 4 seconds. The number of successful predictions decreased,

Abstract:

Facial occlusions can cause both human observers and computer algorithms to fail in a variety of important tasks such as facial action analysis and expression classification. This is because the missing information is not reconstructed accurately enough for the purpose of the task in hand. Most current computer methods that are used to tackle this problem implement complex three-dimensional polygonal face models that are generally timeconsuming to produce and unsuitable for photorealistic reconstruction of missing facial features and behaviour. In this thesis, an image-based approach is adopte

Abstract:

This work is concerned with the problem of 3-D object recognition and orientation determination from single 2-D image frames in which objects may be noisy, partially occluded or both. Global descriptors of shape such as moments and Fourier descriptors rely on the whole shape being present. If part of a shape is missing then all of the descriptors will be affected. Consequently, such approaches are not suitable when objects are partially occluded, as results presented here show. Local methods of describing shape, where distortion of part of the object affects only the descriptors associated wit

Abstract:

The key question of perception is how we manage to get an accurate, unambiguous and phenomenologically complete perception of the real world from proximal stimuli which are generally ambiguous and sometimes incomplete. Given a pattern as a visual input, we usually interpret it in one form although, in general, many interpretations of the pattern are possible. A study of the perceptual preference of partially occluded objects in two dimensional line drawings is presented. Two types of interpretations are considered, mosaic and completion. The interpretation is based on global as well as local s

In Chapter 1 I examine Coetzee’s initial intention, exhibited in a working notebook and early drafts, to rewrite Heinrich Von Kleist’s 1811 novella Michael Kohlhaas, demonstrating how, although Coetzee ultimately move

Then the features of the reference model can also be extracted for matching evaluation. Two categories of features are used in this study. One is transform-invariant and the other is transform-variant. The former is used in the latter matching process to find candidate matching subsequences

Abstract:

碩士<br>國立交通大學<br>控制工程系<br>85<br>Inhis thesis, we propose modified approach for occluded object recognition.In order to extract the target from the background, we use two image sequences that include the same background and the moving target to achieve the objective. First, the two image sequences are chosen to form an absolute difference image. This provides the region of the moving target.After thresholding, we obtain the binary image of the target. We use roll dilation method to obtain the

Abstract:

碩士<br>國立東華大學<br>資訊工程學系<br>99<br>This paper proposes an approach on dependent person to recognize partially occluded and damaged facial expression images, include an iterative face recovery method and a recognition method called the recognition-by-input-approximation (RBIA) method. We use PCA technique to build a person-specific eigenspace for each person identity and a person’s expression-specific eigenspace for each person’s expression. The iterative face recovery method can recover face textures on occluded or damaged area very well. The recovered faces can better preserve personal character
