When using the MTL library, I found that the MTL library does not have a function for finding the value of the determinant. I Googled it and found the following webpage. How to find determinant of nxn matrix? Refer to the instructions in this

Recently, I wrote a program to change the font of the entire interface, but found that something was wrong. The text in the edit control was not left aligned, but shifted several pixels to the right, later I found that the problem occurred when I

Two days ago, I introduced how to build the QT environment and debug simple programs, which may not be very detailed (no picture, it is not intuitive to read the text, But now I still don't understand how csdn can be used as a method). I will

Hydroxyl minerals, including clay minerals and mica, have strong spectral absorption characteristics in short-wave infrared. The absorption position of Al-oh is 2170-2210nm, and that of Si-oh is 2240 ~ 2250nm, Fe-Oh absorption position is

1. Background At present, although theoretically altered minerals (rocks) have very obvious spectral characteristics, due to the insufficient spatial resolution of high (Multi) spectral data, at the same time altered minerals (rocks) it is always a

Previously, vs2008 was used for algorithm writing. Recently, it was necessary to deploy the algorithm on centos and compile the code using gcc. Because a large number of boost libraries are used in the code, it is reasonable to say that there should

The matchtemplate function that uses opencv for template matching is described above. The following describes the internal processing process of the matchtemplate function. The source code of the matchtemplate function is in the

I. Introduction During image processing, statistical values of images are often obtained for calculation. The statistical value of the image here refers to the histogram, maximum value, minimum value, average value, and variance. The following is a

Many remote sensing satellite data must be quantified at a higher level than 8 bits. For example, worldview often uses 12 bits for quantification, and some image processing software cannot directly process 12 bits for quantified images, therefore,

Last year, an algorithm was found in the gdal email list to add an automatic extraction point (GCP) to gdal. After nearly half a year, the matching algorithm in gdal has finally made substantial progress. The current gdal development version (gdal1.1

Currently, many cameras support retaining GPS information when taking photos. This information is generally stored in the EXIF information of JPG images. The following describes how to use the gdal library to read the GPS information in JPG images

For the latest version 1.10.0, the following gdal version still has issues with gdal1.9.2. Recently, we are processing the satellite's long band data. The number of images is about million rows, in raw format. You can use VRT files to conveniently

The tools provided by gdal are very practical. In the future, we plan to write a series of blog posts to briefly describe the tools provided by gdal, and then demonstrate them based on actual examples, hope to be useful for data processing. First,

Most of the time, you need to debug the gdal library, especially when learning how some algorithms in the gdal library are implemented. First, use C ++ for debugging. Take vs2008 as an example. Compile the gdal library of the debug version. For
