ALGORITHMS AND METHODS FOR CALCULATING THE AREA OF A GASTRIC ULCER DEFECT USING MODERN MATHEMATICAL TECHNIQUES

This study proposes a novel integrated methodology for digital processing of endoscopic video signals,
combining automated video analysis, segmentation of pathological structures, and accurate calculation of the gastric
ulcer surface area. A multi-stage algorithm is developed, incorporating intelligent extraction of clinically significant frames,
contour detection of ulcerated regions using combined gradient operators, and construction of an adaptive spline model
for subsequent integral area estimation. Experimental results demonstrate that the proposed approach provides stable
and reliable accuracy and can be effectively used as an auxiliary tool to enhance the objectivity of endoscopic diagnostics.
