Accurate Luminance from Coarsely Quantized Displays
نویسندگان
چکیده
A video signal should use as many bits (gray levels) as possible, to obtain sufficient amplitude resolution for high quality images. However, (digital) displays use a limited number of bits. We propose a modification to the error diffusion algorithm that enables a decrease in the number of bits, without a decrease in luminance accuracy.

Removing Quantization Artifacts in Color Images Using Bounded Interval Regularization
Coarsely quantized images will exhibit false contours in smooth low gradient regions. Images intended for standard displays such as CRT monitors can show contours when moved to high dynamic range devices such as HDR displays and film. While various methods exist for noise removal and image restoration, they are not able to remove these contouring artifacts completely and can impose substantial ...
متن کاملQuantized Constant Envelope Precoding with PSK and QAM Signaling
Coarsely quantized massive Multiple-Input Multiple-Output (MIMO) systems are gaining more interest due to their power efficiency. We present a new precoding technique to mitigate the Multi-User Interference (MUI) and the quantization distortions in a downlink Multi-User (MU) MIMO system with coarsely Quantized Constant Envelope (QCE) signals at the transmitter. The transmit signal vector is opt...
متن کاملGuiding one-dimensional formations of mobile agents with coarsely quantized information
In this paper, we study the formation control problem for platoons of mobile agents that are guided by coarsely quantized information. A comprehensive trajectory-based analysis is presented for the convergence of the multi-agent platoon, which greatly improves the existing result that applies only to 3-agent platoons. Using tools from non-smooth analysis, it is shown that the formation can conv...
متن کاملMethod for Increasing Apparent Amplitude Resolution, and Correcting Luminance Nonuniformity in Projected Displays
Projectors suffer from nonuniformity across the display, as well as spurious contours due to insufficient levels. This work offers an efficient and accurate solution to both problems. A camera-based calibration scheme both measures the spatial luminance nonuniformity and detects the projected levels that are unique. Using this data, an attenuation array is built using reverse-3D-table lookup. T...
متن کاملA Simple Approach to Synthesizing Naïve Quantized Control for Reference Tracking
This paper presents a systematic approach to designing a naïve quantized control law that combines a regular round-to-nearest quantizer with a closed-loop dynamic system to generate a coarsely quantized control force for reference tracking. The naïve quantized control law is derived from minimizing an instantaneous absolute value of a performance-index signal. The stability and performance of t...
