22 results about "Color gradient" patented technology

In computer graphics, a color gradient (sometimes called a color ramp or color progression) specifies a range of position-dependent colors, usually used to fill a region. For example, many window managers allow the screen background to be specified as a gradient. The colors produced by a gradient vary continuously with position, producing smooth color transitions.

A simulation method, apparatus, medium, and device for underfilling of flip chips

ActiveCN121480385BFluid interfaceColor function
This invention discloses a simulation method, apparatus, medium, and device for flip chip underfill, relating to the field of flip chip underfill simulation technology. The invention simulates the flip chip underfill process within a computational domain divided into two meshes in a flow plane perpendicular to the depth direction using a color gradient lattice Boltzmann model. A color function clearly distinguishes between the wetting phase (filler adhesive) and the non-wetting phase (air) to dynamically track the two-phase interface. When simulating the flow field changes during the self-absorption process of flip chip underfill, the average curvature of the interface in the depth direction and the average frictional force of the upper and lower solid walls of the flip chip are introduced to determine the force applied at the two-phase fluid interface, thus reflecting three-dimensional physical effects. While maintaining near-two-dimensional computational costs, this invention significantly improves the accuracy of flip chip underfill simulation and can quickly predict the entire flip chip underfill process at a lower cost.

A fracturing-flowback integrated water lock damage simulation method for a tight gas reservoir

This invention belongs to the field of oil and gas reservoir development and discloses an integrated simulation method for water-lock damage in tight gas reservoirs involving fracturing and flowback. By acquiring scanning data from tight reservoir cores, a binary digital core model reflecting the true pore structure is constructed after preprocessing. A pore-scale two-phase flow numerical calculation model is established using the color gradient multiphase flow lattice Boltzmann method. Based on this model, the fracturing fluid invasion and flowback processes are simulated in an integrated manner, dynamically tracking the migration, distribution, and retention evolution of the water phase in the pore network. The water-lock permeability damage rate is quantitatively determined by calculating the gas phase permeability before and after fracturing fluid invasion. Furthermore, sensitivity analysis is conducted on key factors such as fracturing fluid viscosity, interfacial tension, and reservoir properties. This invention achieves continuous coupled characterization of the entire fracturing-flowback process, revealing the dynamic formation mechanism of water-lock damage at the microscopic level, and solving the problem of poor stability of existing pore-scale simulation methods in high-density gas-water systems.

A green screen foreground edge extraction method based on edge sharpening processing

PendingCN122336324APattern recognitionLocal color
This application provides a method for extracting the foreground edge of a green screen based on edge sharpening processing. First, the original image is acquired and the background and foreground are determined, generating a first mask for initial separation. Edge regions are marked and assigned affixation labels based on the first mask, and color gradient changes and consistency features are calculated to provide a basis for identifying abnormal pixels. An abnormal pixel set is formed by filtering edge pixels under dual conditions to determine the correction target. Reference pixels are filtered based on spatial distance and texture matching, and weighted correction weights are determined to provide an accurate basis for filling. Abnormal pixels are filled using the local color mean and weighted weights to generate a second mask, forming a mask with higher color consistency. The second mask is fused with the target virtual background image; if the boundary gradient change exceeds the limit, feathering is used to eliminate boundary abrupt changes. Finally, the fused image is verified; if continuity is not met, neighborhood interpolation is used for adjustment, and the final image is output, repairing local anomalies and completing the background replacement loop.
