since otherwise it would not be second order. Some experiments plotting1“Linear” in this context means that the unknowns are multiplied only byconstants—they may not be multiplied by each other or raised to any power otherthan 1 (e.g., not squared or cubed or raised to the 1/5 power). Linear[r]

Abstract. In this paper we characterize behavior of the sequence of norm of
primitives of functions in Orlicz spaces by its spectrum (the support of its Fourier
transform).

Correlation theorem states that the Fourier transform of the correlation of two images is the product of the Fourier transform of one image and the complex conjugate of the Fourier transform of the other... because of their tolerance to low image overlap and image scale changes Keypoint indexing[r]

1 Signals and Systems 1.1 INTRODUCTION The concept and theory of signals and systems are needed in almost all electrical engineering fields and in many other engineering and scientific disciplines as well. In this chapter we introduce the mathematical description and representat[r]
