What makes free-hand sketches appealing for humans lies with its capability as a universal
tool to depict the visual world. Such flexibility at human ease, however, introduces abstract …

Human free-hand sketches have been studied in various contexts including sketch
recognition, synthesis and fine-grained sketch-based image retrieval (FG-SBIR). A …

Given an abstract, deformed, ordinary sketch from untrained amateurs like you and me, this
paper turns it into a photorealistic image-just like those shown in Fig. 1 (a), all non-cherry …

The key challenge in designing a sketch representation lies with handling the abstract and
iconic nature of sketches. Existing work predominantly utilizes either,(i) a pixelative format …

Effectively solving the problem of sketch generation, which aims to produce human-drawing-
like sketches from real photographs, opens the door for many vision applications such as …

Humans are able to precisely communicate diverse concepts by employing sketches, a
highly reduced and abstract shape based representation of visual content. We propose, for …

Humans show high-level of abstraction capabilities in games that require quickly
communicating object information. They decompose the message content into multiple parts …

In this paper, we present a method for converting a given scene image into a sketch using
different types and multiple levels of abstraction. We distinguish between two types of …

Modelling human free-hand sketches has become topical recently, driven by practical
applications such as fine-grained sketch based image retrieval (FG-SBIR). Sketches are …

In this work we aim to develop a universal sketch grouper. That is, a grouper that can be
applied to sketches of any category in any domain to group constituent strokes/segments …
