A problem of image preliminary processing filters aperture determination at objects separation by Viener Hopf filtration is considered in the article. There is acquired the expression for processing efficiency in the form of a filter pulse characteristic vectors scalar product and etalon features. This enabled to represent processing efficiency as a quadric form depending on processed image properties and an object being separated. It is shown that for the best separation of an object which can be inserted in a rectangle of a m×n size it is necessary to apply a filter with an (2m+1)×(2n+1) aperture. Results of test images processing are adduced.
