Tangram game consists of seven pieces of polygons such as triangle, square, and parallelogram. Typical methods of image processing for object recognition may suffer from the existence of side thickness and shadow of the puzzle pieces that are dependent on the pose of 3D-shaped puzzle pieces and the direction of light sources. In this paper, we propose an image processing method that recognizes simple convex polygon-shaped objects irrespective of thickness and pose of puzzle objects. Our key algorithm to remove the thick side of piece of puzzle objects is based on morphological operations followed by logical operations with edge image and background image. By using the proposed object recognition method, we are able to implement a stable tangram game applications designed for tablet computers with front camera. As the experimental results, recognition rate is about 86 percent and recognition time is about 1ms on average. It shows the proposed algorithm is fast and accurate to recognize tangram blocks.

In this paper, we study and develop content for a puzzle game that can be enjoyed lightly with appropriate rules us ing Chilgyo-Nori blocks and Tetris blocks. We plan and develop puzzle games with low entry barriers and high revisit rates from the perspective of client indie game developers who are away from mass-produced games that additionally r equire specific items in a specific game section by focusing on the commercialization of game contents. The implement ed game promotes the creativity of users based on the possibility of creating more 2D designs than the existing Chilgy o-nori by using the Tetris block and the Chilgyo-nori block at the same time.
