# 第三阶段：中级图像处理
## 1. 图像滤波
### 目标：
- 学会使用 ` OpenCV ` 进行图像滤波。
### 内容：
- 平滑滤波（均值滤波、高斯滤波）
- 边缘检测（ ` Sobel ` 、 ` Canny ` ）
- 形态学操作（腐蚀、膨胀）
### 实践：
#### 1.1 平滑滤波
- 平滑滤波可以有效去除图像中的噪声，常见的平滑滤波方法…

Thank you for your excellent work, when I use the reconstruction.sh in the repository to predict multiple scenes in MipNeRF360, I find that the reconstruction is not as good as the result in the origi…

### Problem description
I work with image keypoint matching (i.e. SIFT) and I find very useful to visualize keypoints and matches.
When working with matplotlib, the best way for me to visualize them…

### What:
**Removal based on feature matching** involves detecting and analyzing key features in images to identify and eliminate duplicates or overlapping images. This technique uses feature detec…

possible in opencv but seems not possible in airtest? could you please add it so we can match content of "circle" - currently only rectangular?

Hi authors,
Thank you for your repo, i want trainning your model with my custom dataset, i have some question?
1. What is ground truth of your model. i see your generate pair of keypoint using depth…

I tried image matching with the Vocalulary Tree, but one of the eight image sequences would cause the colmap to report an error: the keypoint format was not supported, while the other sequences were a…

I'm using a custom matching algorithm which may produce 1-to-many matches (mostly when scale changes and a single keypoint in an image "splinters" into several keypoints in the other, zoomed-in image)…

Hi,
I am trying to load a set of images that are attached by a set of custom matches. These keypoints and thereby the matches between the images, are evaluated offline by some custom feature extrac…
