Fig. 1. Given a source image downloaded from the Internet, our system generates multiple weak object/attributes cues (a). Using a novel multi-label CRF, we generate per-pixel object and attribute labeling (b). Based on this output, additional verbal guidance: ‘Refine the cotton bed in center-middle’, ‘Refine the white bed in center-middle’, ‘Refine the glass picture’, ‘Correct the wooden white cabinet in top-right to window’ allows re-weighting of CRF terms to generate, at interactive rates, high quality scene parsing result (c). Best viewed in color.

Abstract

Humans describe images in terms of nouns and adjectives while algorithms operate on images represented as sets of pixels. Bridging this gap between how humans would like to access images versus their typical representation is the goal of image parsing, which involves assigning object and attribute labels to pixel. In this paper we propose treating nouns as object labels and adjectives as visual attribute labels. This allows us to formulate the image parsing problem as one of jointly estimating per-pixel object and attribute labels from a set of training images. We propose an efficient (interactive time) solution. Using the extracted labels as handles, our system empowers a user to verbally refine the results. This enables hands-free parsing of an image into pixel-wise object/attribute labels that correspond to human semantics. Verbally selecting objects of interests enables a novel and natural interaction modality that can possibly be used to interact with new generation devices (e.g. smart phones, Google Glass, living room devices). We demonstrate our system on a large number of real-world images with varying complexity. To help understand the tradeoffs compared to traditional mouse based interactions, results are reported for both a large scale quantitative evaluation and a user study.
