Web2 days ago · Solutions to the Vanishing Gradient Problem. An easy solution to avoid the vanishing gradient problem is by selecting the activation function wisely, taking into account factors such as the number of layers in the neural network. Prefer using activation functions like ReLU, ELU, etc. Use LSTM models (Long Short-Term Memory). WebSince the overall SDF voxel structure is still respected, the proposed Gradient-SDF is equally suited for (GPU) parallelization as related approaches. We present Gradient …

Gradient-SDF: A Semi-Implicit Surface Representation for 3D …

WebJul 2, 2024 · SDF is a scalar field in the space domain, which represents the distance from a point in space to the nearest surface in the scene. A positive value is assigned if the point is in the outer region of the nearest surface and negative if it is inside. In this way, it produces a compact representation of the geometry information of a scene. WebNov 26, 2024 · We present Gradient-SDF, a novel representation for 3D geometry that combines the advantages of implict and explicit representations. By storing at every voxel both the signed distance field as well as its gradient vector field, we enhance the capability of implicit representations with approaches originally formulated for explicit surfaces.
