How to make it expand vertically?

Please, see the image I attach.
Imagine the middle rectangle to be an active contour. Is there a way programmatically to make it expand up or down but NOT left or right, until a specific row? The row shall be estimated by a gray pixel value. The first row Matlab meets this x gray value.
Is it possible?
Thanks

See your former question: https://www.mathworks.com/matlabcentral/answers/441297-scan-the-image-until-the-first-and-last-points-i-set . Another duplicate of this question was closed already.
This seems to be the contour of a lossy JPEG compressed image. This will impede the automatic detection of edges massively. Is there really no way to obtain clean and clear inputs?
