This article is primarily concerned with graph theoretic approaches to image segmentation applying graph partitioning via minimum cut or maximum cut. Segmentation-based object categorization can be viewed as a specific case of spectral clustering applied to image segmentation.
Minimum Normalized Cut Image Segmentation. • Normalized cut [1,2] computes the cut cost as a fraction of the total edge connections to all the nodes in the graph. Advantage: Being an unbiased measure, the Ncut value with respect to the isolated nodes will be of a large percentage compared to the total connection from small set to all other nodes.

Solve (D – A)x = λDx for the eigenvectors with the smallest eigenvalues 3. Let x2= eigenvector with the 2ndsmallest eigenvalue λ2. 4. Threshold x2to obtain the binary-valued vector x´2. such that ncut(x´2) ≥ncut(xt 2) for all possible thresholds t 5. For each of the two new regions, if ncut < threshold T, then recurse on the region.
With its educational objectives based on enhancement of students’ practical skills, the Department adopts the educational objectives of NCUT (to cultivate quality talents that have “professional knowledge, humanistic literacy, social care and international perspectives”) and the development philosophy of the College (innovation, pragmatism and cooperation) to be core values, to cultivate ...
NCUT is a unique university of technology. It is a school that was donated to the country by citizens and restructured. Holding the spirit of taking from society to benefit society, the founders, General Chang Ming and Ms. Wang Kuo-Hsiu, had realized their philosophy by setting an example. “ Education is nothing but a concern for role model.
