Problems solved by technology

Although the above algorithm can provide more visual information for specific numerical regions (such as high-density numerical regions and high-border regions, etc.), due to the limited number of colors in the original color table, it is inevitable to reduce the color encoding other numerical regions. It is difficult to achieve a global balance, which is not conducive to data visual exploration
Although some methods provide interactive methods such as region-of-interest selection (ROI, region-of-interest), due to the relatively complex optimization process, the calculation time is relatively long, and the efficiency in large-scale data exploration is relatively low.

Abstract

The invention belongs to the technical field of human-computer interaction, and provides a visual exploration method and system for color embedding. The method includes: acquiring two-dimensional scalar field data; mapping a selected initial color table to the two-dimensional scalar field data; embedding one or more colors into the color embedding positions in the initial color table of the two-dimensional scalar field data; The embedded color table is mapped to the 2D scalar field data to output a color-optimized visualization.

Description

technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to a visual exploration method and system for color embedding. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The exploration of scalar field data is an important task in scientific data visualization. For example, changes in ocean currents are closely related to the salinity and temperature of seawater. Color is an indispensable visual coding element for expressing scalar field data, and it is the most widely used. Color visualization generates a visual image rich in visual information by establishing the mapping relationship between the colormap and the data (that is, the color map). However, due to the limited number of colors in the color table, the diversity of scalar field data and pattern features, it is di...
