Image Uniform Color
Feature Description
Image uniform color is an image preprocessing technique that aims to adjust the color, brightness, and contrast of multiple images involved in mosaicking, eliminating tone inconsistencies caused by different shooting seasons, sensor variations, or weather conditions, thereby achieving a uniformly colored and visually coordinated DOM mosaic result.
This function is only used for the image uniform color operation in the UAV data processing workflow.
SuperMap ImageX Pro It is supported starting from the 2026 version.

Parameter description
| Parameter Name | parameter interpretation | parameter type |
| color balancing method | Specifies the method for image uniform color. Currently, only local color balancing is supported. | ColorBalanceMethod |
| Resolution | Sets the ground resolution of the color balance result image, in m/px. The default value is 0. When the value is 0, it is automatically calculated. | Double |
| No Data Value | Sets the pixel value for no-data areas in the result image. The default value is 0.0. | Double |
| Fusion Pyramid Level | Sets the number of fusion pyramid levels. The default value is 3, with a range of [1, 6]. | Integer |
| Downsampling Factor | Performs downsampling on the original image, which can improve the speed of feature extraction and matching, but may reduce the accuracy of partial matching. The default value is 0, meaning a suitable downsampling factor will be automatically calculated. | Integer |
| Template Block Size | The template block size. The default value is 10000, with a range of [1000, 50000]. | Integer |
| output format | Sets the storage type for the result image. Options include Not Set, Tiff/GeoTIFF, Erdas Image, and PCIDSK. The default is Tiff/GeoTIFF, which means using the original storage type of the image for output. | FileType |
| compression method | Available only when Output format is Tiff/GeoTIFF. The default is NONE. For more method introductions, please refer to Compression Method. | CompressMethod |
Output Result
The orthophoto image data after color balancing.
