要解决第一个问题,可以生成多个mask,分别表示 full object,或者object的一部分,作者采用了5个mask,分别表示 full,bottom/top/left/right halves,记为 mh,h∈{full,bottom,top,left,right} 。上面所述的DNN回归检测则是其中 full object 这个特殊情况。这5个mask肯定是过完备的(冗余的),但是正是这种过完备性才...
1、First, a single object mask might not be sufficient to disambiguate objects which are placed next to each other.单个对象的 mask 不能有效的检测放在一起的多个物体 2、Second, due to the limits in the output size, we generate masks that are much smaller than the size of the original image...
一种更加激进的方法是对于多种不同的类别使用同一个定位器,这似乎也是可行的。 5.2 - Object Localization from DNN output 为了完成检测过程,我们需要去对每一张图像评估一系列边界框。虽然输出的分辨率小于输入图像,但是我们将二进制掩码调整大小为与输入图像一样的分辨率。任务的目的是在输出的掩码做表中评估出边...
1、为了解决以上的 问题,生成多个的mask,每一个即代表全部的物体也代表物体的一部分, 2、由于我们的最终目标是产生一个边界框,我们使用一个网络(模型)来预测Object Box Mask和四个额外的网络来预测四个半框,即Bottom, Top, Left 和 Right 半框。对于,, 如果相同类型的两个对象彼此相邻放置,则所产生的5个Bina...
第一,模型输出的单个Object Mask无法有效地对相互靠近的歧义Objects进行对象检测;第二,由于模型输出大小的限制,所生成的Obinary Mask的尺寸相对于原始图片显得及其小,譬如:400×400400×400,d=24d=24,那么每个输出对应到原始图片的单元大小大约为16×1616×16,故无法精确地对对象进行定位,而在原始图片更小的时候,...

DIGITS 4 introduces a new object detection workflow that allows you to train networks to detect objects (such as faces, vehicles, or pedestrians) in images and define bounding boxes around them. See the postDeep Learning for Object Detection with DIGITSfor a walk-through of how to use this ...
A full object mask is generated by providing the input image to a first deep neural network object detector that produces a full object mask for an object of a particular object type depicted in the input image. A partial object mask is generated by providing the input image to a second ...
