Programming computer vision in C / C++

unsigned char* data;. } image;. This code creates a struct called image that contains three member variables: width to hold the number.

Secure Coding in C++: Integers

Example 1: Color-to-Grayscale Image Processing

The input image is encoded as unsigned characters [0 255]. __global__ void colorConvert(unsigned char * grayImage

• std::nullptr_t

  std::nullptr_t is the type of the null pointer literal, nullptr. It is a distinct type that is not itself a pointer type or a pointer to member type. Its values are null pointer constant (see NULL), and may be implicitly convertedto any pointer and pointer to member type. sizeof(std::nullptr_t) is equal to sizeof(void*).

• Data Models

  The choices made by each implementation about the sizes of the fundamental types are collectively known as data model. Four data models found wide acceptance: 32 bit systems: 1. 1.1. LP32 or 2/4/4 (int is 16-bit, longand pointer are 32-bit) 1.1. 1.1.1. Win16 API 1.1. ILP32 or 4/4/4 (int, long, and pointer are 32-bit); 1.1. 1.1.1. Win32 API 1.1.2. U...

• Range of Values

  The following table provides a reference for the limits of common numeric representations. Prior to C++20, the C++ Standard allowed any signed integer representation, and the minimum guaranteed range of N-bit signed integers was from ?(2N?1?1)?(2N?1?1)-(2N-1 -1) to +2N?1?1+2N?1?1+2N-1 -1 (e.g. -127 to 127 for a signed 8-bit type), which corresponds...
