Facial caricature drawing based on subjective impressions

Abstract

SUMMARYIn conventional studies of facial caricature drawing, image processing of a face picture is performed, and feature points are extracted. A caricature is drawn based on these points. On the other hand, there have been few studies of facial caricature drawing based on impressions, which are subjective and dependent on the person who views the face. The purpose of this paper is to draw a facial caricature using linguistic expressions in order to reflect personal impressions of a face. Cheerfulness, gentleness, and so on are considered as impressions of a face. The drawn facial caricature can be modified by the use of linguistic terms. The concept of exaggeration, which is important for emphasis of personality in a caricature drawing, is also introduced by considering the line thickness and the exaggeration rate. Facial caricatures are evaluated by subjects who themselves draw them by the presented method, and also by other subjects, and the validity of the process is discussed

A Feature Extraction Method for Retrieving Traditional Japanese Crafting Objects

“…In traditional Japanese crafting, not only the key-words and indexes but also the feeling process is very important. For this reason, we 16 developed a Knowledge Agent (KA) to retrieve suitable designs based on each user's feeling. For retrieving information, the KA uses a knowledge-base, which is based on the relation between people feeling, presentation space and objects.…”

“…The goal is to provide the users with the desired presentation space. Recently, there have been many researches about Kansei information engineering, which include the data clustering method [9,10,11], Kansei information quantification method by using fuzzy or neural network [12,13,14,15,16,17], visualization interface of image feature space [18] and Kansei retrieval method [19,20,21,22,23] .…”

3D face synthesis based on the information of words expressing facial features

“…Some words might directly express the physical dimension and shape of facial elements, while other words might abstractly or metaphorically express the shape of facial elements. There are some studies to synthesize human faces based on fuzzy information about the faces [2], [3]. The words used in the studies, however, are strictly limited to several words that directly expressing the physical dimension and shape, i.e.…”

A Method to Synthesize Three Dimensional Face Models by Mapping from a Word Space to a Physical Model Space and the Inspection of the Mapping Function

“…In former studies on synthesis of a human face by utilizing the information of words, only few words describing directly the physical features were used, and the words explaining some degree of physical dimension, i.e., "slight," "a little," "very," and so on, were simply added to Ref. [4].…”
