Latent finger print recognition plays an important role in forensic, criminal cases etc. The latent images will not be recognised easily since they are impartial images, which find difficult to match with the registered database. Due noisy it is very for recognition. Autoencoder pre-processing image. ConvNetbased method efficient approach used image For each minutiae extraction, ConvNet descrip...

This paper presents a minutiae detection procedure based on adaptive tracing the gray-level ridge of the "ngerprint image with piecewise linear lines of di!erent length. The original "ngerprint image is smoothed with an adaptive-oriented smoothing "lter only at some selected points. This will greatly reduce the computational time. Each ridge in the skeleton is labeled with a number so that each...

—In this paper a 3D plant modeling method based on projection image is presented. A novel simple 3D reconstruction algorithm is proposed and its calibration speed and precision are analyzed. Min-cross section algorithm and Ball B-spline are applied to extract the skeleton of the reconstructed image and to fit the meshes respectively. Experiments show that the reconstructed columnar root, branch...

Recently, a skeletonization algorithm for volumetric objects has been proposed. In this paper, we show that this algorithm cannot obtain correct results in the sense that both the connectivity and topological information of the original object cannot be maintained. Index Terms Skeleton, centerline, voxel-coding, distance transform Qingmao Hu and Wieslaw L. Nowinski are both with Kent Ridge Digi...
