Shape and Texture of Coarse Aggregate01:25

Shape and Texture of Coarse Aggregate

Aggregate shape is classified based on the relative sharpness or roundness of the edges and corners. This classification includes categories like rounded, angular, elongated, and flaky, each with specific characteristics. Rounded aggregates, fully shaped by attrition, are typical of river or seashore gravel, while angular aggregates, such as crushed rock, have well-defined edges. Aggregates that are elongated and flaky are less desirable, as they can reduce the workability and strength of...
Gestalt Principles of Perception01:21

Gestalt Principles of Perception

Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...
Visual Agnosia01:12

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...

Aggregates Classification01:29

Aggregates Classification

Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...
Structural Classification of Joints01:20

Structural Classification of Joints

Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

Area of Science:

  • Computer Vision
  • Computer Graphics
  • Digital Art

Background:

  • Non-photorealistic rendering (NPR) often benefits from image segmentation.
  • Existing NPR techniques have not focused on classifying the shapes within image segments.
  • Artistic styles like those of Matisse involve shape simplification.

Purpose of the Study:

  • To introduce a novel shape classification method for image segments in NPR.
  • To enable the creation of abstract artwork by simplifying image regions into basic geometric shapes.
  • To incorporate user subjectivity in the shape selection process for personalized artistic output.

Main Methods:

  • A shape classifier is developed that inputs image regions from a segmentation hierarchy.
  • The classifier outputs the "best" fitting simple shape (e.g., circle, square, triangle) for each region.
  • The classifier is trained by a user, allowing subjective preferences to guide shape selection over purely geometric measurements.

Main Results:

  • The shape classification approach effectively contributes to NPR from photographs.
  • The system produces abstract artwork by emulating artistic styles that favor shape simplification.
  • The trained classifier operates automatically, with options for user interaction to refine results.

Conclusions:

  • Shape classification is a valuable tool for advancing non-photorealistic rendering.
  • User-guided shape simplification allows for the creation of personalized abstract art.
  • This method offers a novel approach to generating artistic interpretations of photographic images.
