Abstract	Hand posture recognition has tremendous potential in the field of natural user interactions. There were many advances in research in recent years but there are still limitations regarding its usage in unfavorable live situations where hand posture variation, illumination change or background complexity are an issue. In cases like these, recognizing the hand posture is a difficult task. As such, we considered reducing the difficulty of the task by using curriculum learning with intermediate information. We proceeded to divide the complex architecture of the hand posture recognition task into two easier ones: 1) Extraction of the hand shape under clutter background with illumination change, 2) Recognition of the hand posture from a binary image. In order to do so, we propose here a bottom-up structured deep convolutional neural network incorporating a special layer for binary image extraction. Our proposed method also employs state-of-the art techniques for deep learning to obtain generalization. As a result, we achieved better recognition performances of the hand posture under clutter background compared to the baseline method.
