Introduction UIViewController is a key part of iOS application. If you implement a ViewController with storyboard/xib, you use @IBOutlet attribute. Which access level do you give those variables? public , internal or private . I often use private . It makes codes concealed and independent from outside. This is good, but…

2. Smoothing Smoothing is a technique for reducing noise on the basis of spatial filter. Same as edge detection, determining kernel K is our interest. Gaussian Filter Gaussian filter is one of smoothing filter. Each kernel matrix element is determined by gauss function. This distribution has the following characteristics give more weight at the…

1. Edge Detection Edge detection is one of spatial filtering. Edge is the outside limit of an object. At edges, the image’s luminance changes drastically. Edge detection is to calculate a position luminance changes drastically in the image. How to calculate the position? Use differential. In continuous domain, the image’s derivatives is where…

Introduction This is a basic section. Others here. 1. Edge Detection, Prewitt, Sobel and Laplace 2. Smoothing, Gaussian and Bilateral Basic Image Processing is a method to perform some operations on an image. getting an enhanced image extracting some information, like edges Metal render advanced 3D graphics and perform data-parallel computations using…

3. Coroutines and Immutability of K/N — Coroutines What is coroutines? This official guide is very helpful for understanding what is coroutines and how to use coroutines. This chapter’s topic is to use coroutines in K/N and its current status. Updating Gradle To use Coroutines in K/N, update dependencies insharedNative/build.gradle . kolinx-coroutines-core-common and kotlinx-coroutines-core-native are new. One more, in…

2. Creating Simple Framework with Describing Some K/N Features — iOS Specific Codes in Kotlin We configured K/N project previously. In this chapter, let’s create simple framework with K/N features. First, create iosMain/kotlin/actual.kt directories and file in the same way as we did here.
