isat's Issues

当单张图标注的多边形过多时,每次保存卡顿严重

使用您的软件在团队内最近进行了一批标注,中间遇到多个同学提到标注后期每次多边形保存时都会卡顿(20s左右),简单推理了下,应该是这么个情况:
目前软件内部逻辑是每次画完多边形+选择类别后,都会保存一次。但是标注后期多边形数量增加,json文件过大,所以每次保存时占用的时间都很大。

我想可能现有的保存逻辑稍作修改可以解决?前几年我们使用过另一款基于LabelImg修改来的LabelImgPlus软件,它的逻辑是每次标注后先缓存下来不会马上保存到它的xml文件中,而是当点选save按钮时才会将前面所有的未保存标注存下来。
这软件后期我们也发现保存时间较长,应该和后续xml/json文件内容过多有关。但该软件的逻辑使得用户可以标注很多个多边形之后再保存,所以更为合理。

label_convent tool的代码可能存在问题

经过标注后,使用标注文件转换器转换成PNG图片时,转换的图片色彩在边缘上会出现渐变。例如背景色黑色(0,0,0)时,类别颜色(0,200,0),在类别颜色和背景颜色相接的地方颜色会出现(0,0-200,0)的过渡色。(比如(0,125,0),实际上应当不存在该种类别和色彩)

这样的标注文件进行深度学习训练时可能会出错。主要问题是导致无法和网络的输出进行对应,难以计算损失函数。一般来说在类别颜色交界的地方应该是直接跳变的。可能是/tools/label_convert.py代码逻辑存在问题。
