How to search for an object on the image using a fully-connected neural network

Hello, the task is to find an object in an image using a fully-connected neural network with Keras, Theano, in Python. Currently, the network configuration is as follows:

   def   Create_encoding_layers  ():  keel =  3   filter_size =  64   parade = ""> 1    Pool_SIZE =  2    retu  [ zeropadding = (paD, paAD)),  convolution2d (Filter_size, Keel, Keel, Keel, Keel, Keel, Keel, Keel, Keel, Keel, Keel border_mode =  'valid' ),  Batchnormalization (),  Activation ( '' relu '),  Maxpooling2d (pool_size = (pool_size, pool_size)),  ze
