: To separate cracks from other dark features (like shadows or oil spots), experts use geometric properties such as Length/Width ratio , Compactness , or Asymmetry to isolate long, thin objects.

The first step involves capturing high-resolution images or LiDAR data. These are then converted to grayscale to highlight intensity discontinuities. Segmentation : eCognition uses algorithms like Multiresolution Segmentation (MRS) to group pixels into meaningful "objects". Noise Reduction

eCognition is a software tool used for object-based image analysis, change detection, and geospatial data extraction. It is developed by Definiens, a company that specializes in image analysis and geospatial intelligence solutions. The software is widely used in various industries, including environmental monitoring, urban planning, agriculture, and natural resource management.

: It considers the geometry and texture of a crack, not just its color.
