Two roads to change detection with Picterra

Picterra offers two distinct approaches to cater to your diverse change detection needs. Delve into the world of change detection with us as we explore the comparative change detection analysis and the change detection model.

The comparative change detection analysis

Detect

Detect objects/textures separately in 'before' and 'after' images.

Compare

Compare detections to identify disappearances, appearances or identify moving objects.

Decide

Create change alerts dashboard for manual review if required.

The change detection model

PAIR & ANNOTATE

Combine "before" and "after" images then simultaneously annotate targeted changes across paired images.

TRAIN

Train the model with combined image pair and change annotations.

Detect

Run trained (single) model on combined image pair and detect changes.

Dive deeper into change detection methods enabled in Picterra platform

Toolbox

Change detection toolbox

Streamline change detection workflows in Picterra using an array of specialized features, empowering you to expedite the process while tailoring it precisely to your needs.

Split view

Streamlining annotation process

Platform feature that splits your imagery into two halves. One side presents the “before” image, while the other showcases the “after” image (with customizable order). Annotations on one side seamlessly populate on both images, streamlining your workflow.

Format images for change detection

Format images for change detection

Advanced data processing

Advanced tool allowing you to combine two images – the “before” and “after” – into a single input image facilitating both change detection training and subsequent detection processes.

Simple change detection

Change detection comparison

Advanced data processing

Advanced tool with customizable parameters to suit your use case enabling comparison of geolocated polygons generated by Picterra detectors to identify changes.
