Minimization problem image processing

Hello,
I'm trying to minimize this function (by p):
where:
p is a NxN image
k is NxN image
tc is NxN image
* is the convolution of image k and image p
grad() is the gradient of the image
||·||_L1 is the L1 norm
||·||_L2 is the L2 norm
theta is a constant
I need a little bit of help coding this one in vector form.

I have looked at some implementations without the convolution, but this part is just throwing me off. I have read Young's inequality but don't know how to implement it.
