Ambiguous stimulus material was computer-generated by superimposing image components of a target-face and either a random checkerboard texture or a masking face. The recognition of the target-face was studied both for foveal and extrafoveal vision. Compensation of the peripheral disadvantage in image discrimination by rescaling the stimulus size was possible only in the case of texture. Comparable results were obtained from combining band-pass image components of the portraits. Results suggest that it is the relative inability to recover a signal from spatially correlated noise that characterizes visual discrimination in the peripheral visual field.
模糊刺激材料是通过将目标面部的图像成分与随机棋盘纹理或掩蔽面部叠加而由计算机生成的。针对中央凹和中央凹外视觉研究了目标面部的识别。仅在纹理的情况下，通过重新调整刺激大小来补偿图像辨别中的外周劣势才是可能的。从组合肖像的带通图像成分中获得了可比的结果。结果表明，在外周视野中，视觉辨别特征在于相对无法从空间相关噪声中恢复信号。
