有没有办法检测主要投资回报率？ [英] Is there a way to detect the main ROI?

问题描述

我希望在图片中检测重要的ROI元素。 （我想得到这个职位）
我已经测试了一个还原的 SeamCarving-Method 。我希望，图片中最重要的区域具有最大的能量水平。我已经生成了一个垂直和一个水平的Seam并占据了交叉点。但这种方法似乎并不完美。
一些例子：

i want detect the important ROI Element in a picture. (i want to get the position) I've tested a reverted SeamCarving-Method. I hoped, that the most importand Area in a picture have the most energylevel. I've generated one vertical and one horizontal Seam and took the intersection. But this method don't seem to be perfect. Some examples:

near aceptable; good detection http://img440.imageshack.us/img440/7459/seamflower.jpg

更糟糕的检测：

很好的检测http://img836.imageshack.us/img836/5766/seamsun.jpg （也许这点很好结果。这是图片中最大能量水平的点。）

good detection http://img836.imageshack.us/img836/5766/seamsun.jpg (maybe the point is a good result. It's the point with the max. energylevel in this picture)

有没有人想要更好地检测roi的想法？

Have anyone a idea to detect roi's more better?

推荐答案

我认为您正在寻找的关键术语是：显着性检测，突出物体检测等

I think the key terms you are looking for is: Saliency Detection, Salient Object Detection, etc

也许这些论文会指出您正确的方向：

Perhaps these papers will point you in the right direction:

• 基于显着性的快速场景分析视觉注意模型（ PDF ）


• 在自然图像上模拟人类Saccadic扫描路径（ PDF ）


• 按构图进行的突出物体检测（ PDF ）


• 显着性过滤器：用于显着区域检测的基于对比度的过滤（ Web ）

• A Model of Saliency-Based Visual Attention for Rapid Scene Analysis (PDF)
• Simulating Human Saccadic Scanpaths on Natural Images (PDF)
• Salient Object Detection by Composition (PDF)
• Saliency Filters: Contrast Based Filtering for Salient Region Detection (Web)
