SOLUTION: The interpolation signal processing circuit is characterized by providing a slanting correlation judgment part 8 which detects combination of real pixels with the highest correlation among combinations of two actual pixels located in the vertical direction or the slanting direction of the image ...
Compared to the straight-forward implementation of interpolation by upsampling the signal by stuffing it with L-1 zeros , then filtering it, you save memory by a factor of (L-1)/L. In other words, you don’t have to store L-1 zero-stuffed “upsamples” per actual input sample. 3.4....

For interpolation of a single variablex, the ordered set of tuplesis known, such that= {(x0, y0), (x1, y1), …, (xn, yn)}, wherexifori= 0, 1,…,nis sorted in increasing order, then the interpolating function, orinterpolant,f(x) is determined, such thatf(xi) =yi...
VIDEO SIGNAL PROCESSING CIRCUIT when an interlaced signal is converted to a progressive signal, memories are needed in memory unit resulting in high costs, and a simple two-dimensional digital filter performs interpolation in a field to impair a feeling of sharpness ... S Kazunori,千田 和則,K...

The FFT algorithm is associated with applications in signal processing, but it can also be used more generally as a fast computational tool in mathematics. For example, coefficients ci of an nth degree polynomial c1xn+c2xn−1+...+cnx+cn+1 that interpolates a set of data are comm...
2 Signal model 2.1 Coprime array configuration Consider a coprime array as illustrated in Fig. 1, which is composed of two sub-arrays. One sub-array has N sensors with the inter-element spacing of Md, and the other consists of M sensors with the inter-element spacing of Nd. Here, M an...
