I was wondering what's the statement"

y = (bboxes(:,2)-1) / resizeRatio + 1;        
yfoot = min(length(obj.pedScaleTable), round(y + height));

" means in the example'tracking pedestrians from a moving car. thanks.

% y = (bboxes(:,2)-1) / resizeRatio + 1; this gives the y-coordinate of the top of the bounding box in the original image. The image being processed is resized commented in line 230.

% yfoot = min(length(obj.pedScaleTable), round(y + height)); This gives the y-coordinate of the bottom of the bounding box. The auxiliary table was constructed such that you can retrieve the estimated height of an adult from the table using yfoot as an index. Therefore, this index value cannot go beyond the size of the table.
