What are some effective techniques in change detection?
Change detection techniques are methods used to identify differences in data over time. Common techniques include image differencing, post-classification comparison, and change vector analysis.
Can you explain image differencing?
Image differencing involves subtracting one image from another to highlight changes. It's often used in remote sensing to detect land use changes.
What are the advantages of using change vector analysis?
Change vector analysis provides a comprehensive view of changes by analyzing the direction and magnitude of changes in multi-dimensional data.
Are there any limitations to these techniques?
Yes, limitations include sensitivity to noise, the need for high-quality data, and potential misinterpretation of changes.
