Noise Removal from Surface Respiratory EMG Signal
The aim of this study was to remove the two principal noises which disturb the surface electromyography signal (Diaphragm). These signals are the electrocardiogram ECG artefact and the power line interference artefact. The algorithm proposed focuses on a new Lean Mean Square (LMS) Widrow adaptive structure. These structures require a reference signal that is correlated with the noise contaminat...
متن کاملSurface Fitting Using Implicit Algebraic Surface Patches
1 Introduction 2 Interpolation and least-squares approximation provide! efficient ways of generating Ck.continuous meshes of surface patches, necessary for the consLrucLion of accurate computer geometric models of solid physical objects [see for e.g. [8.7]. Two surfaces J(:I;, Y,z) = 0 and g(x, y, z) = 0 meet with Ck-continuity along a curve C if and only if there exists functions a:(x, Y, z) a...
متن کاملIntrinsic Image Decomposition Using Structure-Texture Separation and Surface Normals
While intrinsic image decomposition has been studied extensively during the past a few decades, it is still a challenging problem. This is partly because commonly used constraints on shading and reflectance are often too restrictive to capture an important property of natural images, i.e., rich textures. In this paper, we propose a novel image model for handling textures in intrinsic image deco...
متن کاملDetermining Surface Type From Surface Normals
By exploiting the relationship which exists between the Gaussian image and gradient space, the two representations can be utilized in conjunction to facilitate the interpretation of a set of surface normals. The projection of the Gaussian image onto a plane can provide clear traces which quickly yield general knowledge of the underlying surface.
متن کاملPeople Detection in 3d Point Clouds Using Local Surface Normals
The ability to detect people in domestic and unconstrained environments is crucial for every service robot. The knowledge where people are is required to perform several tasks such as navigation with dynamic obstacle avoidance and human-robot-interaction. In this paper we propose a people detection approach based on 3d data provided by a RGB-D camera. We introduce a novel 3d feature descriptor ...
