the normal and lateral line cycloid scales of a cyprinid fish; alburnoides bipunctatus (blotch, 1782) have been subjected to sem to study their detailed structure. it shows the general architectural pattern of a cycloid cyprinid scale. the focus of the scale is clear and sharp located in the anterior field. circuli are observed in all fields. primary radii which originate from very near the foc...

Software product line engineering is regarded as a promising approach to generate tailored software products by referencing shared software artefacts. However, converting software legacy into a product line is extremely difficult, given the complexity, risk of the task and insufficient tool support. To cope with this, in this paper, we proposed a top-down feature-mining framework to facilitate ...

A large number of features can be used to represent on-line handwritten signatures in verification tasks. Depending on the signature database and acquisition conditions, some features will not help in separating writers in the feature space so that an appropriate decision boundary will be hard to estimate. Other features will provide good separability between legitimate system users and their f...

In this paper we analyze applications of Douglas-Peucker algorithm to compression and feature line extraction of 3D models from digital scans introducing a multiresolution model that enables a fast description of the object at different levels of details through the use of a unique rearrangement, stored in a file, of the input data set. The multiresolution algorithm, which reaches high data com...

We will demonstrate an object tracking algorithm that uses a novel simple symmetric similarity function between spatially-smoothed kernel-density estimates of the model and target distributions. The similarity measure is based on the expectation of the density estimates over the model or target images. The density is estimated using radial-basis kernel functions which measure the affinity betwe...

Abstarct. An improved method using feature line extraction is described for automatically generating hexahedral meshes for complex geometric models that automate the normally interactive operations (such as model editing). Testing showed that the time taken for these interactive operations was significantly reduced, making it possible to quickly generate hexahedral meshes with sufficient qualit...

A new approach called shortest feature line segment (SFLS) is proposed to implement pattern classification in this paper, which can retain the ideas and advantages of nearest feature line (NFL) and at the same time can...

This paper proposed high level feature for online Lao handwritten recognition. This feature must be high level enough so that the feature is not change when characters are written by different persons at different speed and different proportion (shorter or longer stroke, head, tail, loop, curve). In this high level feature, a character is divided in to sequence of curve segments where a segment...

In many tracking applications, adapting the target appearance model over time can improve performance. This approach is most popular in high frame rate video applications where latent variables, related to the objects appearance (e.g., orientation and pose), vary slowly from one frame to the next. In these cases the appearance model and the tracking system are tightly integrated, and latent var...
