RESUME iv INTRODUCTION 1 TECHNIQUES AND METHODS 2 IMAGE PREPROCESSING AND MASKS GENERATION 4 INDIVIDUAL TREE CROWN DELINEATION 6 INDIVIDUAL TREE CROWN CLASSIFICATION 10 ACCURACY ASSESSMENTS 11 INDIVIDUAL TREE CROWN REGROUPING AND STAND GENERATION 12 THE TREE-TOP APPROACH 14 FOREST INVENTORY APPLICATIONS 16 CONCLUSION 22 REFERENCES 23 Cover Image – Results of species classification and regrouping of individual tree crowns and tree clusters over the original panchromatic IKONOS image (1 m/pixel) for part of a 10 000 ha area (11.7 x 8.6 km2) in the Lac a lʼOurs region of Quebec that was analyzed with the individual tree crown approach. This work was done in collaboration with CLC-Camint (Gatineau) and Industries Davidson Inc. and was funded in part by the “Programme de mise en valeur des ressources du milieu forestier Volet 1” of the Quebec Department of Natural Resources. The tree species in the forested areas are indicated by the following colours:

How this classification was reachedexpand

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
