Edge detection technology aims to identify and extract the boundary information of image
pixel mutation, which is a research hotspot in the field of computer vision. This technology …

This paper surveys the field of nonphotorealistic rendering (NPR), focusing on techniques
for transforming 2D input (images and video) into artistically stylized renderings. We first …

Single image super-resolution (SISR) deals with a fundamental problem of upsampling a
low-resolution (LR) image to its high-resolution (HR) version. Last few years have witnessed …

This paper presents an approach for image cartoonization. By observing the cartoon
painting behavior and consulting artists, we propose to separately identify three white-box …

Recent extensions to the standard difference-of-Gaussians (DoG) edge detection operator
have rendered it less susceptible to noise and increased its aesthetic appeal. Despite these …

QR code is a popular form of barcode pattern that is ubiquitously used to tag information to
products or for linking advertisements. While, on one hand, it is essential to keep the …

We address the problem of fast, large scale sketch-based image retrieval, searching in a
database of over one million images. We show that current retrieval methods do not scale …

We present a non‐photorealistic rendering technique to transform color images and videos
into painterly abstractions. It is based on a generalization of the Kuwahara filter that is …

We address the problem of large scale sketch based image retrieval, searching in a
database of over a million images. The search is based on a descriptor that elegantly …

We describe an object replacement approach whereby privacy-sensitive objects in videos
are replaced by abstract cartoons taken from clip art. Our approach uses a combination of …
