#将Image对象转换成ndarray对象,方便opencv读取 im_array = np.array(bg_im) # 此时im_array为rgb模式,而OpenCV为bgr模式,我们通过下面语句将rgb转换成bgr bgr_im_array = im_array[:, :, ::-1] 1. 2. 3. 4. 5. 6. 最后bgr_im_array就是我们最终的返回结果。 (5)写入视频 为了节约空间,我并非...
sys.exit(app.exec_()) 这个就比较重要的了,因为在我写程序的时候,关闭一个窗口再显示另一个窗口的时候,会出现一个段错误,使用gdb python工具调试时具体报错如下 Thread 1 "python3" received signal SIGSEGV, Segmentation fault. 0x00007fffdd4dc1a2 in QHash<unsigned int, QXcbWindowEventListener*>::findN...

13g. Compared to the Otsu method, all OSF detections are correct, which proves its efficiency in the segmentation of uneven illumination images. 5. Conclusions To develop an all-weather, real-time and automatic flow measurement system using single camera, an image-based method for in-situ water...

It is possible to get polygon-based segmentation from Tesseract: with BlockPolygon from the page iterator delivered by AnalyseLayout. There is a bug somewhere though: sometimes, paths self-intersect, which even Tesseract itself does not cope with very well (as can be seen by the mask images ...
(However, we establish that a level set may be used effectively as a final step in a process.) While progress has been made to develop automatic segmentation techniques appropriate for mitochondria [2, 11–15] and cells [16–20], there remains a need for more accurate, rapid, and robust...
Therefore, the uncertainty associ- ated with dosimetry measurements is reduced; (c) We have introduced elements of automation to improve efficiency of data collection and processing, incor- porated histogram segmentation for assessment of non-uniformity, and proposed methods to reduce pro- hibitive ...
