1. A method for neural network operations by using a grid generator, comprising steps of:

  • (a) a computing device, if a test image is acquired, instructing a non-object detector to acquire non-object location information for testing, including information on where non objects for testing are located on the test image, and class information of the non-objects for testing, including information on classes of the non-objects for testing, by detecting the non-objects for testing on the test image;

    (b) the computing device instructing the grid generator to generate section information, which includes information on a plurality of subsections in the test image, by referring to the non-object location information for testing;

    (c) the computing device instructing a neural network to determine parameters for testing, to be used for applying the neural network operations to either (i) at least part of the subsections including each of the objects for testing and each of non-objects for testing corresponding to said each of the objects for testing, or (ii) each of sub-regions, in each of said at least part of the subsections, where said each of the non-objects for testing is located, by referring to parameters for training which have been learned by using information on non-objects for training whose corresponding class information is same as or similar to that of the non-objects for testing; and

    (d) the computing device instructing the neural network to apply the neural network operations to the test image by using each of the parameters for testing, corresponding to each of said at least part of the subsections, to thereby generate one or more neural network outputs.
