Applying Filter To Images: iOS
<p>When we enter the realm of CoreImage we have to deal with <strong>CI</strong> objects. It can be CIImage, CIFitler or something else.</p>
<p>It will be better to take a step back and understand how CoreImage applies “Filter” on Image. If you are wondering if your app will get a performance hit due to the use of filters then you need not worry. The Core Image uses <strong>GPU </strong>for<strong> </strong>processing images. (FYI GPUs in general are way faster than CPUs.)</p>
<h2>Three Cs of CoreImage</h2>
<ol>
<li><strong>CIContext</strong><br />
This is responsible for doing image analysis as well as rendering image processing results. Creating CIContext is a heavy operation hence it’s recommended to reuse existing ones instead of creating new ones.</li>
</ol>
