Abstract: Video encoding using variance may include generating a first input variance based on pixel values from a first block from a first frame from an input video stream, generating a first encoded block by encoding the first block, generating a first reconstructed block by reconstructing the first encoded block, generating a first reconstruction variance based on pixel values of the first reconstructed block, comparing the first input variance and the first reconstruction variance to detect a visual artifact in the first reconstructed block, generating a second encoded block by encoding a second block from a second frame from the input video stream, wherein encoding the second block includes selecting an encoding mode based on the detection of the visual artifact in the first reconstructed block, including the second encoded block in an output bitstream, and storing or transmitting the output bitstream.

Abstract: Disclosed herein are implementations of systems, methods, and apparatuses for video encoding using variance. One aspect of the disclosed implementations includes a method for encoding a video stream that includes generating a first input variance based on pixel values of a first block of a first frame of the video stream, generating a first reconstruction variance based on pixel values of a reconstructed first block that is reconstructed from an encoding of the first block, comparing the first input variance and the first reconstruction variance to detect a visual artifact in the reconstructed first block, and encoding a second block of a second frame of the video stream using an encoding mode that is selected based on the detection of the visual artifact in the reconstructed first block by the comparison.

Abstract: A method for forming flanged end of an inner conductor of a coaxial resonator at one end of the conductive body. The flange is formed integral to the conductive body by flaring the end of the conductive body. The size and shape of the flange are selected to achieve a desired capacitance surface area for use in a resonator. A combination of expanding tool and calibration tool are used to control the size and shape of the flange that will be formed on the end of the conductive body.

Abstract: A method and apparatus for making an inner conductor from a conductive body integrally forms a flange on one end of the conductive body. The flange is formed integral to the conductive body by flaring the end of the conductive body. The size and shape of the flange is selected to achieve a desired capacitance surface area for use in a resonator. A resonator housing that has a plurality of cavities can be provided with a plurality of conductive bodies that are inserted into holes located in a bottom wall of the resonator body and that protrude into the plurality of cavities. The resonator housing and conductive bodies are placed onto a flanging fixture to produce a flange on each conductive body of a desired size and shape to achieve a desired capacitance surface area. The plurality of conductive bodies can be simultaneously flanged and fastened to the base of the resonator housing.
