The Core image is a powerful filter processing framework. In addition to the image can directly add a variety of built-in filters, but also to accurately modify the brightness, color, exposure, and so on, the following two examples show how to add a filter to UIImage.1, Sepia filter-CisepiatoneThis is a bit retro old photo yellow effect (above one is the original image).to extend the UIImage class, add a tan filter:
I have a software on my phone to implement a lot of image filters, very interesting, I intend to try.This filter is mainly for old photo effects.The code is short, and I won't go into it in detail.Original:Post-processing effects:The MATLAB code is as follows:Clear All;close all;clc;img=imread ('lena_rgb.jpg'); [H W K]=size (IMG); Imshow (IMG); R=double (IMG (:,:,1)); G=double (IMG (:,:,2)); B=double (IMG (:,:,3) ); RR=r*0.393+g*0.769+b*0.198; RG=r*0.349+g*0.686+b*0.168; RB=r*0.272+g*0.534+b*0.1

First, the camera working principleIn the previous article we talked about the composition of the camera module, working principle, as a kind of understanding. Let's analyze how the camera works from the register angle. How to read the camera spec (use key parameters for driver tuning, take GT2005 as an example).The sp
GLSurfaceView is a class in OpenGL and can also be used to preview Camera. It is unique in previewing Camera. Where is the uniqueness? When Surfaceview is powerless and hard to solve, GLSurfaceView can only be used. It can truly separate the data and display of Camera, for example, Camera only enables preview and does

Camera is the camera class for Android camera hardware, located under the hardware package "Android.hardware.Camera". It is mainly used for camera capture pictures, start/stop preview pictures, take photos, get video frames, etc., it is the local service, responsible for managing the
Google has output TextureView from Android4.0. Why? This is to make up for Surfaceview's shortcomings. On the other hand, it is also to balance GlSurfaceView. Of course, this is my speculation. The relationships between TextureView, Surfaceview, SurfaceTexture, and GLSurfaceView will be analyzed after the artist launches GLSurfaceview preview Camera. This article describes how to preview Camera with Texture
The simple project we implemented in the previous article, and now we continue to add features for this camera. First, in Camera, we can perform simple control over the Camera. When we need to configure more functions, we need to use the Parameters class under Camera. The Parameters class encapsulates most of the funct
