Transfer of content-aware vignetting effect from paintings to photographs
This paper discusses how the vignetting effect of paintings may be transferred to photographs, with attention to center-corner contrast. First, the lightness distribution of both are analyzed. The results show...

Interactive Local Hue Contrast Manipulation
The lightness and saturation of an image may be subject to adjustment for the purpose of aesthetic improvement. Normally, this is in the form of a contrast adjustment. Such an adjustment would work upon the ma...

The Geometric Attributes of Paintings
Within a painting, two forms of geometry can be identified: 2D and 3D. 2D geometry is defined by such things as the corner, the centre, the edge and the middle. 3D geometry is defined as simplified planes, suc...

Composition Improvement for Portrait Photographs
Composition has a great impact upon the visual quality of a photograph. This chapter studies the composition in portrait paintings and proposes an algorithm to improve the composition of portrait photographs b...

Defining Hue Contrast
Quantifying the style of visual art has long been a challenging yet largely overlooked problem. Of key importance in the style of a painting is the manner in which the artist has employed hue. We propose a mea...

Chapter
The Portrait and Landscape Genres
While contemporary paintings come in every conceivable form, pre-modern paintings were understood in terms of only five categories or ‘genres’, with some genres being more important than others. These genres, ...

Computational Models of Colour Contrast
In the previous chapter, colour contrast was examined as phenomena within the art domain. In this chapter, we review computational models that might be employed to define these phenomena. In the engineering do...

Chapter
Global Colour Style Transfer
In this chapter, we examine the global chromatic and achromatic aspects of a painting. Their organisation is particular to each artist, with work by that artist showing consistency in its contrast organisation...

The Colour Attributes of Paintings
In order to understand a phenomenon, one must be able to navigate it: to name its parts and to know its up from its down. Colour is a great challenge in this respect, being dimensionally very complex. This cha...

Chapter
Atmospheric Perspective Effect Transfer for Landscape Photographs
The atmospheric perspective effect is a physical phenomenon relating to the effect that atmosphere has on distant objects, causing them to be lighter and less distinct. The exaggeration of this effect by artis...

Chapter
Regional Contrast Manipulation for Portrait Photograph Enhancement
This chapter proposes a method to manipulate the regional contrast in snapshot style portrait photographs by using pre-modern portrait paintings as aesthetic examples: to improve the visual appeal and focus of...

Aesthetic Interactive Hue Manipulation for Natural Scene Images
One of the most common ways to adjust the aesthetic quality of a natural scene image is by editing its color. However, while lightness and saturation manipulation is well understood in computational terms, hue...

Active Contour with a Tangential Component
Conventional edge-based active contours often require the normal component of an edge indicator function on the optimal contours to approach zero, while the tangential component can still be significant. In re...

Application of SVMs to the Bag-of-Features Model: A Kernel Perspective
The Bag-of-features model has recently achieved great success in image categorisation and become the state of the art. Support vector machines (SVMs) have played an important role in this process. This chapter...

Kernel Machines for Imbalanced Data Problem in Biomedical Applications
Kernel machines such as the support vector machines (SVMs) have been reported to perform well in many applications. However, the performance of a binary SVM can be adversely affected by an imbalanced set of tr...

Region-Based Nasopharyngeal Carcinoma Lesion Segmentation from MRI Using Clustering- and Classification-Based Methods with Learning
In clinical diagnosis of nasopharyngeal carcinoma (NPC) lesion, clinicians are often required to delineate boundaries of NPC on a number of tumor-bearing magnetic resonance images, which is a tedious and time-...

A Linear Programming Based Method for Joint Object Region Matching and Labeling
Object matching can be achieved by finding the superpixels matched across the image and the object template. It can therefore be used for detecting or labeling the object region. However, the matched superpixe...

Human Detection with Occlusion Handling by Over-Segmentation and Clustering on Foreground Regions
Two-dimensional image based human detection methods have been widely used in surveillance system. However, detecting human in the presence of occlusion is still a challenge for such image based systems. In thi...
