The antique stereophonic recording and playback format is going to be replaced by new surround sound formats in the near future. At the moment, various surround techniques are being investigated in many artistic and technical applications. The main concern is to find an appropriate recording and playback format which supports the natural spatial hearing cues. Therefore, surround sound systems s...

Pointillism is a branch of impressionism that can be dated back to the late 19th century. It is a painting technique that only uses tiny, distinct dots to form patterns of color. It enjoys a duality in being both discrete up close as dots and continuous from distance as patterns. Combining this artistic inspiration with the techniques of digital image processing, we developed an image-processin...

We present dense medial descriptors, a new technique which generalizes the well-known medial axes to encode and manipulate whole 2D grayvalue images, rather than binary shapes. To compute our descriptors, we first reduce an image to a set of threshold-sets in luminance space. Next, we compute a simplified representation of each threshold-set using a noise-resistant medial axis transform. Finall...

This paper proposes a non-photorealistic rendering method that creates an artistic effect called mosaicing. The proposed method converts images provided by the user into the mosaic images. Commercial image editing applications also provide a similar function. However, these applications often trade results for low-cost computing. It is desirable to create high quality images even if the computa...

We present a novel algorithm for stylizing photographs into portrait paintings comprised of curved brush strokes. Rather than drawing upon a prescribed set of heuristics to place strokes, our system learns a flexible model of artistic style by analyzing training data from a human artist. Given a training pair — a source image and painting of that image — a non-parametric model of style is learn...

This paper presents an overview of the image-morphologic primitives used commonly in non-photorealistic rendering (NPR), a subdomain of computer graphics that is inspired by a long tradition of artistic and illustrative depiction. In particular, we survey NPR shading, stroke-based rendering, sparse line drawings, graftals, and area primitives. Such primitives usually cover larger regions on the...

Recent works in image editing are opening up new possibilities tomanipulate and enhance input images. Within this context, we leverage well-known characteristics of human perception along with a simple depth approximation algorithm to generate non-photorealistic renditions that would be difficult to achieve with existing methods. Once a perceptually plausible depth map is obtained from the inpu...

Non-photorealistic rendering (NPR) is an area of computer graphics that studies artistic expressions for digital art. Unlike traditional computer graphics that emphasizes photorealism, NPR explores a wide variety of artistic styles including painting, sketching, and animated cartoons, and develops algorithms for recreating them. One art form that is largely unexplored in computer graphics is Op...

Abstract. The angel is a mythological character common to the Turkic peoples. Along with spread of Islam and glorification God, its angels also became popular praised. duties responsibilities four great given in Qur’an, as well people’s views understanding them, have been mentioned works written over centuries become synonymous kindness honesty, purity chastity. article focuses on use everyday ...
