Abstract: Let S be a compact connected subset of $ {R^d}$. A necessary and sufficient condition is given to ensure that the dimension of the convex kernel of S is greater than or equal to k, $ 0 \leqq k \leqq d$. This condition involves a visibility constraint on the points of local nonconvexity of S. As consequences, we obtain new characterizations of the convex kernel of S and the nth-order convex kernel of S.
