Adaptive strategy for superpixel-based region-growing image segmentation
Mahaman Sani Chaibou, Pierre-Henri Conze, Karim Kalti +2
This work presents a region-growing image segmentation approach based on superpixel decomposition. From an initial contour-constrained over-segmentation of the input image, the ima…
A combined Approach Based on Fuzzy Classification and Contextual Region Growing to Image Segmentation
Mahaman Sani Chaibou, Karim Kalti, Bassel Soulaiman +1
We present in this paper an image segmentation approach that combines a fuzzy semantic region classification and a context based region-growing. Input image is first over-segmented…
The threshold EM algorithm for parameter learning in bayesian network with incomplete data
Fradj Ben Lamine, Karim Kalti, Mohamed Ali Mahjoub
Bayesian networks (BN) are used in a big range of applications but they have one issue concerning parameter learning. In real application, training data are always incomplete or so…
Image segmentation by adaptive distance based on EM algorithm
Mohamed Ali Mahjoub, karim kalti
This paper introduces a Bayesian image segmentation algorithm based on finite mixtures. An EM algorithm is developed to estimate parameters of the Gaussian mixtures. The finite mix…
