The simulation results indicate the method ′ s superiority to the traditional wavelet-based image fusion method in terms of both visual quality and objective evaluation criteria. 结果表明,相比于传统小波域内的图像融合算法,该方法得到的融合结果具有更良好的视觉质量和更优的量化指标,体现出更强的融合性能。
Therefore, the visual quality is unsatisfied on both the subjective and the objective quality, so effective postprocessing scheme for compressed image is urgently demanded. 这样,无论是图像的主观质量,或是客观质量都受到较大的损失,很难满足人眼对图像质量的要求,所以,人们迫切需要一些高效的针对压缩图像的后处理方法。
The color measurement relying solely on subjective visual judge cannot satisfy the incessant growth of high quality requirements, so it must be combined with the objective of the survey. 色彩评价仅仅依靠主观的视觉评判远远不能满足日益发展的高品质印刷要求,所以必须结合客观的色彩测量。
Objective To study the visual function ( VF ) and quality of life ( QOL ) of the patients affected by the cataract extraction that was operated by blind prevention medical group in short time. 目的了解农村防盲医疗队短期集中开展的白内障手术对患者视功能(visualfunction,VF)和生存质量(QualityofLife,QOL)的影响。
Objective To evaluate the visual status, visual function and quality of life ( VF / QOL ) in the patient with cataract treated by phacoemulsification. 目的评价白内障超声乳化术后患者的视力、视功能(visualfunction,VF)和生存质量(QualityofLife,QOL)。
