Then, we propose a new triangulation procedure for mesh structure and also a new algorithm to justify connectivity of mesh structure after motion vector estimation of the mesh points. We modify the occlusion-adaptive, content-based mesh design and forward tracking algorithm used by Yucel Altunbasak for selection of points for triangular 2-D mesh design. This is achieved by allowing no node points within the background to be covered and refining the mesh structure within the model failure region at each frame.

In this algorithm, connectivity of the mesh elements (patches) across covered and uncovered region boundaries are broken. To overcome this limitation, BTBC (background to be covered) detection and MF (model failure) detection algorithms are being used. However, available uniform 2-D mesh model enforces connec-tivity everywhere within a frame, which is clearly not suitable across occlusion boundaries.

#Dmesh triangulation software
"Latest project that utilises a very similar technique is DMesh, a custom software made in Cinder by Dofl Yun.Two-dimensional mesh-based motion tracking preserves neighboring relations (through connectivity of the mesh) and also allows warping transformations between pairs of frames thus, it effectively eliminates blocking artifacts that are common in motion compensation by block matching. "DMesh turns any image into a techy artowrk." - Fastcompany This allows users to control number of mesh dynamically so realistic result having more meshes or abstract one having less meshes can be made easily. Video import/export is in the works.ĭynamic Mesh Density Control (Pro version only): Import/export sequenced images automatically, making it easier for motion designers. Working with Sequenced Images (Pro version only):
#Dmesh triangulation manual
Where other tools only allow manual use, DMesh analyzes the image, adds points and plays with the density accordingly while reducing noise in the mesh.Ĭontrol the number of mesh points dynamically: add more for a realistic result, or subtract to make the image more abstract.ĭMesh suuport to export images as bitmaps, vectors or 3D data for maximum flexibility and scope.Īuto Point Generation is built based on computer vision technology so the results are closer to the original source and working with animation files can get more continuity between frames and less noise in the mesh. You’ll get an idea of how you use Dmesh for your project.ĭMesh provides auto-generated points, which is useful for people doing animations or larger batches of images. To build the program, a groundbreaking mix of computer vision technologies were employed to make DMesh for someone without any design background.Ĭheck user showcase at the DMesh site. It works by analyzing an image and generating a triangulation pattern for a beautiful finished product. DMesh is a custom creative application that turns images into techy artwork.
