    • A method is provided for automatically providing a digital image rating of photo retouching. The method includes the step of receiving at a computer, including a processor, a first set of pixel data of an original image and a second set of pixel data of a retouched image. The method also includes using the processor to determine a plurality of geometric statistics and a plurality of photometric statistics from the first and second sets of pixel data. The method further includes the step of using the processor to quantify a rating of the retouched image based upon the geometric statistics and photometric statistics to indicate deviation of the retouched image from the original image. A system is also provided to perform the steps.
    • 提供了一种用于自动提供照片修饰的数字图像评级的方法。 该方法包括在计算机处接收包括处理器的原始图像的第一组像素数据和经修饰的图像的第二组像素数据的步骤。 该方法还包括使用处理器从第一和第二组像素数据确定多个几何统计信息和多个测光统计信息。 该方法还包括使用处理器基于几何统计和光度统计来量化修饰过的图像的等级以指示经修饰的图像与原始图像的偏差的步骤。 还提供了一个系统来执行这些步骤。

    • An pulse electro thermal defrost evaporator system has multiple refrigerant tubes formed from an electrically conductive metal and connected in parallel for refrigerant flow. These tubes are, however, connected electrically in series. A controller is capable of detecting ice accumulation and connecting the tubes to a source of electrical power for deicing when it is necessary to deice the tubes. Embodiments having a manifold having multiple conductive sections insulated from each other are disclosed for coupling tubes electrically in series. Alternative embodiments with a single, long, wide-bore, tube are disclosed, as are embodiments having an evaporating pan coupled in series or parallel with the tubes, and embodiments with thermal cutoff and electrical safety interlocks.
    • 脉冲电热除霜蒸发器系统具有由导电金属形成并且并联连接用于制冷剂流动的多个制冷剂管。 然而,这些管串联电连接。 控制器能够检测冰积聚并将管连接到用于除冰的电源以用于除冰管。 公开了具有彼此绝缘的多个导电部分的歧管的实施例,用于串联电耦合管。 公开了具有单个,长的,宽孔的管的替代实施例,其中具有与管串联或平行耦合的蒸发盘的实施例以及具有热切断和电安全互锁的实施例。
