Compensation of White Point Shift Generated from Tone Compression in iCAM
نویسندگان
چکیده
Recently, a new image appearance model, designated iCAM06, was developed for High-Dynamic-Range (HDR) image rendering. The dynamic range of a HDR image needs to be mapped on the range of output devices, which is called the tone reproduction or tone mapping. The iCAM06, the representative HDR rendering algorithm also uses the tone compression for image reproduction on the dynamic range of output devices, however occurs white point shift during its tone compression process. Therefore, we propose compensation method for white point shift using the corrected channel gain. Experiment results show that the proposed method has better performance than the iCAM06.

Separate Color Correction for Tone Compression in HDR Image Rendering
Many High-Dynamic-Range (HDR) rendering techniques have been developed. Of these, the image color appearance model, iCAM, is a typical HDR image rendering algorithm. HDR rendering methods normally require a tone compression process and include many color space transformations from the RGB signal of an input image to the RGB signal of output devices for the realistic depiction of a captured imag...
متن کاملColor Correction for Preserved Saturation and Hue in HDR images
The iCAM06 has been used as an image appearance model for HDR image rendering. iCAM06 goes through the color space conversions of the several steps to present HDR images. The dynamic range of a HDR image needs to be mapped onto the range of output devices, which is called the tone mapping. However, tone compression process of iCAM06 causes white point shift and color distortion because of color...
متن کاملA New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)
This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...

It has been shown that frequency-place mismatch has detrimental effects on English speech recognition. The present study investigated the effects of mismatched spectral distribution of envelopes on Mandarin Chinese tone recognition using a noise-excited vocoder. In Experiment 1, speech samples were processed to simulate a cochlear implant with various insertion depths. The carrier bands were sh...

Background and aims: Epidemiological studies have shown a significant correlation between awkward back posture and low back pain among carpet weavers. Therefore, this study aims for estimating cumulative compression load among carpet weavers during a shift work. Methods: In this study, the awkward back postures of 4 male and 9 female carpet weavers were monitored, using electronic inclinometer...
