Embodiment Construction
[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0050] Figure 1(a) is a 3D face image; (b) is an image sequence generated by Gabor filtering; and (c) is a video shot with a 3D effect brain structure map; they are in order of 3rd order, 3rd order and 4th order tensor save;
[0051] The following formula shows the tensor HOSVD decomposition principle:
[0052]
[0053] Among them, A is the N-order tensor, and S on the right is the core tensor (generally sparse), Represents an orthogonal matrix (projection) acting on the i-th dimension of A.
[0054] figure 2 It is a kind of video compression system and method based on HOSVD algorithm, and this video compression system comprises: camera equipment and corresponding sensor, described camera equipment and corresponding sensor are respectively connected with CPLD processor and FIFO memory, and described CPLD processor and FIFO me...
