MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202618057815 A) filed by Lg Electronics Inc. on May 06, 2026, for Non-Separable Primary Transform Design Method And Apparatus.
Inventors include Choi, Jungah; Choi, Jangwon; Lim, Jaehyun; and Kim, Seunghwan.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: According to the disclosure of the present document, by configuring a primary transform to include a non-separable transform, higher encoding efficiency may be expected compared to the existing primary transform including only a separable transform. Also, by applying a non-separable primary transform using residual characteristics of a current block or neighboring block, the number of bits required for signaling information related to a nonseparable transform kernel may be reduced, and more efficient compression performance may be obtained. In addition, even though a non-separable transform has higher computational complexity or memory requirements than a separable transform, computational complexity and power consumption may be reduced through the disclosure of the present document.
