When writing a reconstruction algorithm, it is necessary to use the point coordinate and the normal data file, and then use the normal calculation module in the PCL to generate the normal direction. The post-output method contains curvature information in the file, but this is not required. Then wrote a Python small script to implement the format conversion.#--coding:utf-8--Import TimeImportNumPy as NP fromSysImportArgvscript, Input_file=Argvinput_dat
file format for Photoshop image processing software, with the file name extension. PSD, which can support various image features of layers, channels, masks, and different color modes, is a non-compressed original file Save format. Scanners cannot directly generate files of that fo
OIn Digital image processing, there are specific processing algorithms for different image formats. So, before we do the image processing, we need to think about the format of the image we want to design and implementation of the algorithm. Based on this requirement, this pa
Jpg
The JPG full name is JPEG. A JPEG picture stores a single raster image in 24-bit color. JPEG is a platform-independent format that supports the highest level of compression, although this compression is lossy. An asymptotic JPEG file supports interleaving.

You can increase or decrease the level of JPEG file compression. However, the file size is at the expense of
