![]() ![]() ![]() (I always try to leave my BC sketches as just ink, but colour is too tempting, and I can’t resist adding it). In both cases I started with the left eye. On my first BC I forgot the nose, and on the second, the hair was too small for the head. Therefore, in addition to the 5,000 drawings accepted, we have 1,947 rejected submissions, which can be used in setting up an automatic quality guard. Sketching is like a muscle and needs training. The quality control is realized through manual inspection by treating annotations of the following types as rejection candidates: (1) missing inner boundary, (2) missing important objects, (3) with large misalignment with original edges, (4) the content not recognizable, (5) drawing humans with stick figures, (6) shaded on empty areas. In order to obtain high-quality annotations, we design a labeling interface with a detailed instruction page including many positive and negative examples. The biggest is that there is no shading involved. Although contour lines help illuminate a form, there are a couple of important characteristics of them. ![]() With contour drawing, we are focusing on the. To sketch an object, you typically use this type of line to define a shape on paper, canvas, and beyond. The Turkers are asked to trace over a fainted background image. The first thing we do when beginning to draw is contour drawing, which is another name for drawing the outline. The drawings have strokes roughly aligned for image boundaries, making it easier to correspond human strokes with image edges.The dataset is collected with Amazon Mechanical Turk. In this dataset, there are 1,000 outdoor images and each is paired with 5 human drawings (5,000 drawings in total). We present a new dataset of paired images and contour drawings for the study of visual understanding and sketch generation. ![]()
