  human visual
     Combined with other results of our laboratory about the development of CB-and PV-containing neurons in the neocortex of human prenatal brain, the present result suggests that development and maturation of the neurons in area 17 of human visual cortex are earlier than that in area 18.

     In this paper,one coding error measure based on human visual perceptivity is defined. Furthermore one novel VQ coding scheme is proposed. Experimental results prove that decoded images using it have better subjective quality.
     传统矢量量化编码一般采用绝对误差(如MSE)为误差度量准则,并不符合人类视知觉的特性.本文根据人的视觉感知规律,定义了一种可广泛用于图象编码的视觉误差准则(MVE),由此导出一种新的矢量量化编码方法.实验表明,采用这种方法得到的解码图象在视觉效果比传统方法有较大改善.

Efficiency of the Human Visual System in Discrimination of Dynamic Images
      
The efficiency of the human visual system during the observation of motionless test objects with additive dynamic Gaussian quasi-white noise was studied.
      
Efficiency of the Human Visual System in Recognition of Moving Objects
      
The relationships studied between the efficiency of the human visual system for recognition of moving objects in the presence of dynamic additive quasi-white Gaussian noise and the duration of object presentation are studied.
      
The comparisons are made using the mean square error, the mean absolute error, and a subjective human visual error criterion.

An adaptive visual primitive image coding method is presented in this paper. Based on the existed human visiual system model, a series of visual primitives, which are designed independent of the statistical properties of natural image but dependent on the properties of human visual neuroes, are used to segment and match the image to be coded. The visual primitives which are best matching with the local areas of natural image are then coded. This method is simple in computation and easy to realization. It is...

An adaptive visual primitive image coding method is presented in this paper. Based on the existed human visiual system model, a series of visual primitives, which are designed independent of the statistical properties of natural image but dependent on the properties of human visual neuroes, are used to segment and match the image to be coded. The visual primitives which are best matching with the local areas of natural image are then coded. This method is simple in computation and easy to realization. It is found that subjectively more pleasing decoded image is obtained at relative high compression rates at 21:1 to 30:1.

本文给出一种自适应视觉基元图象编码方法(Adaptive Visual Primitive Image Coding),它利用了现有的人类视觉系统模型及研究结果,采用一系列独立于自然图象统计特性而与人类视神经元特性紧密相关的视觉基元,对图象进行分割、匹配运算,进而对与自然图象局部区域最佳匹配的视觉基元进行编码,具有运算简单、实现方便的优点.计算机模拟实验表明,在较高数据压缩比(21:1~30:1)时,解码图象的主观质量令人满意.

Absolute error measures such as MSE are used in conventional VQ coding schemes. But they don't suit for human visual perception. In this paper,one coding error measure based on human visual perceptivity is defined. Furthermore one novel VQ coding scheme is proposed. Experimental results prove that decoded images using it have better subjective quality.

Distribution of calbindin (CB)-and parvalbumin (PV)-containing neurons in areas 17and 18 of the visual cortex of 28-week human fetus was investigated by means ofimmunocytochemistry. Much more CB-and PV containing neurons were found in area 17 thanin area 18. In addition, many CB-and PV-containing neurons in area 17 also appeared in14relatively superficial layers, when compared with those neurons in area18. Thus, the areas 17/18 border was easily identified. Combined with other results of our laboratory about...
