To compare JPEG and RAW image file extensions to direct measurement of the breast region.
Points were marked on the breasts and arms of 40 female volunteers. The joining of these points in each hemibody formed seven linear segments, one angular segment and one median segment common to both hemibodies. Volunteers were photographed in a standardized fashion and evaluated by three raters using the software Adobe Photoshop CS6® and three image file extensions (RAW, high resolution JPEG and low resolution JPEG); values were compared to direct anthropometry.
All variables had interclass correlation coefficient higher than 0.8 (ICC>0.8). On average, all variables in all methods showed differences (p<0.05) when compared to direct measurement. A formula was created for each segment and each image file extension in comparison with the direct measurement.
Measurements were similar among the correlated JPEG and RAW image file extensions but differed from the actual breast measurement obtained with a caliper.
比较JPEG和RAW图像文件扩展名与乳房区域直接测量的结果。
在40名女性志愿者的乳房和手臂上标记点。这些点在每个半侧身体上的连接形成了七个线性段、一个角段和一个两个半侧身体共有的中间段。志愿者以标准化方式拍照,并由三名评估者使用Adobe Photoshop CS6®软件和三种图像文件扩展名(RAW、高分辨率JPEG和低分辨率JPEG)进行评估;将所得值与直接人体测量结果进行比较。
所有变量的组内相关系数均高于0.8(ICC>0.8)。平均而言,与直接测量相比,所有方法中的所有变量均显示出差异(p<0.05)。针对每个段和每个图像文件扩展名,与直接测量相比创建了一个公式。
相关的JPEG和RAW图像文件扩展名之间的测量结果相似,但与用卡尺获得的实际乳房测量结果不同。
