This paper presents a method to apply progressive transmission to line drawings using the wavelet transform. Experiments have been conducted and showed that the wavelet transform, combined with a quantization step, performs progressive transmission using a data rate comparable to standard chain coding at the expense of almost no visually perceptible distortion.

The formal mathematical definition of a Jordan curve (a non-self-intersecting continuous loop in the plane) is so simple that one is often lead to the unimaginative view that a Jordan curve is nothing more than a circle or an ellipse. In this paper, we continue a discussion of others [1, 2, 9, 11] that a Jordan curve can be quite fantastical both in some bizarre properties such a curve might ha...

A subset A of a metric space (X, d) is central iff for every Katětov map f : X → R upper bounded by the diameter of X and any finite subset B of X there is x ∈ X such that f(a) = d(x, a) for each a ∈ A ∪ B. Central subsets of the Urysohn universal space U (see introduction) are studied. It is proved that a metric space X is isometrically embeddable into U as a central set iff X has the collinea...

This article explores the issue of posthuman embodiment envisioned in contemporary Chinese artist Tian Xiaolei’s (田晓磊) two representative videos: The Creation (Chuangzao “创造,” 2015) and Greatness (Weida “伟大,” 2017). Perceived envisaged from an erotic perspective, reveals humans’ unrestrainable lust desires for fusing with technology, while Greatness, by taking a different trajectory remaking Bu...

Object detection is an important step in automated scene understanding. Training state-of-the-art object detectors typically require manual annotation of training data which can be labor-intensive. In this paper, we propose a novel algorithm to automatically adapt a pedestrian detector trained on a generic image dataset to a video in an unsupervised way using joint dataset deep feature learning...
