comverting a cell to an image

i have a cell y of size as below
y =

    [128x128 double] {1x3 cell} {1x16 cell}

y{1,2}:


ans =

    [128x128 double] [128x128 double] [128x128 double]

y{1,3}


ans =

  Columns 1 through 4

    [64x256 double] [64x256 double] [64x256 double] [64x256 double]

  Columns 5 through 8

    [64x256 double] [64x256 double] [64x256 double] [64x256 double]

  Columns 9 through 12

    [256x64 double] [256x64 double] [256x64 double] [256x64 double]

  Columns 13 through 16

    [256x64 double] [256x64 double] [256x64 double] [256x64 double]

the above matrix was obtained while decomposing a single image in different directions
i need to convert this cell to an image
each matrix in this cell is an image which is decomposed in different directions so each matrix should be converted to an image and on superimposing all the image i will get the quality image
please any one help me to do this
