CROSS-LEVEL IMAGE BLENDING

摘要

One or more techniques and/or systems are provided for image blending and/or facilitating image transitions. In an example, a map interface displays map information, such as of a town, through a visualization. A first image having a first level of detail and a first image type (e.g., satellite imagery of the town) may be displayed through the visualization. While zoomed into the town, a second image having a second level of detail and a second image type (e.g., aerial imagery of the town) may be displayed through the visualization. Instead of merely transitioning the visualization from displaying the first image to displaying the second image (during zooming), which may otherwise provide a visually abrupt transition, one or more intermediate blended images, having intermediate levels of detail between the first image and the second image, may be generated and displayed during the transition between the first image and the second image.

主权项

1. A method for image blending, comprising:
generating an intermediate blended image between a first image, having a first image type and a first level of detail, and a second image having a second image type and a second level of detail, the intermediate blended image having an intermediate level of detail between the first level of detail and the second level of detail, the generating comprising:
performing structure transfer upon the first image to generate a new image;downsampling the second image to generate a downsampled image having a downsampled size corresponding to a size of the new image;computing a color difference between the new image and the downsampled image;upsampling the color difference to generate an upsampled color difference; andblending a gradient image using an interpolation weight and the upsampled color difference to generate the intermediate blended image; and displaying the intermediate blended image through a visualization during a transition between display of the first image and display of the second image.
