Three-dimensional nonrigid reconstruction based on probability model
International Journal of Advanced Robotic Systems, 2020 Most nonrigid motions use shape-based methods to solve the problem; however, the use of discrete cosine transform trajectory-based methods to solve the nonrigid motion problem is also very prominent.

Discrete cosine transforms on quantum computers [PDF]
ISPA 2001. Proceedings of the 2nd International Symposium on Image and Signal Processing and Analysis. In conjunction with 23rd International Conference on Information Technology Interfaces (IEEE Cat. No.01EX480), 2002 A classical computer does not allow to calculate a discrete cosine transform on N points in less than linear time. This trivial lower bound is no longer valid for a computer that takes advantage of quantum mechanical superposition, entanglement, and interference principles.

Directional Analytic Discrete Cosine Frames
IEEE Access, 2022 Block frames called directional analytic discrete cosine frames (DADCFs) are proposed for sparse image representation. In contrast to conventional overlapped frames, the proposed DADCFs require a reduced amount of 1) computational complexity, 2) memory ...

ECG synthesis via discrete cosine transform [PDF]
Images of the Twenty-First Century. Proceedings of the Annual International Engineering in Medicine and Biology Society, 2003 Results on the modeling and synthesis of the electrocardiogram (ECG) from its component waves after a suitable transformation are presented. The transformed components add up to the transform of the complete beat and thus allow synthesis of the ECG. Pole-zero modeling of the transformed signals by the Shanks method proved very successful. >

Cyclic Wiener Filtering Algorithm in Discrete Cosine Transform Domain for Vibration Signal
MATEC Web of Conferences, 2016 In order to solve the problem that the effect of using cyclic Wiener filter directly to remove the noise on the non-stationary vibration signal is poor, the paper applies discrete cosine transform to the cyclic Wiener filter, proposing the cyclic Wiener ...
