Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The cv::Mat variable's image refers to the input image, while result refers to the binary output image."

A block of code is set as follows:

// compute distance from target color 
if (getDistanceToTargetColor(*it)<=maxDist) { 
        *itout= 255; 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

Mat scores = outs[i].row(j).colRange(5, outs[i].cols);
Point classIdPoint;  
double confidence;  // Get the value and location of the maximum score

Any command-line input or output is written as follows:

cd llvm_root

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "You then click on Build Solution in Visual Studio."
