Trained on millions and millions of real world images, not artificial lab data, the Clipping Magic Auto-Clip AI handles so much more than just a few cherry-picked foreground categories. And the learning hasn't stopped. As the AI is exposed to more and more photos, it's ability to handle yours continues to improve. Fully automatic hair handling coming soon! In the meantime, just mark the hair yellow. Then adjust the colors, add shadows and reflections, and crop the image to create a truly professional result, all in one easy-to-use tool!

It has saved me SO much time already! Is your photo crooked or washed out? Is the white balance off?

Configure your default settings for effortless color correction and consistent cropping on every image. The result will be uniform, professional shots in every edit. Yesterday actually. It's a great tool. The Scalpel Tool allows you to get the clip just right in low-contrast areas of the image.

Clipping Magic can help you separate out hair from clean and distinct backgrounds. Gradients and some noise typically work, as long as the colors involved are sufficiently different. Go far beyond clipping paths, alpha masks, and the magic wand with our custom-built background eraser.

The images all had different background colors, and I needed them to all have a uniform look. You may need to add your company logo to a new image or add an icon to a PowerPoint presentation. Luckily, the approach is similar no matter what tool you are using.

With Snagit, it only takes a few steps to quickly remove the background from your image. Keep in mind, Snagit is not as sophisticated as a professional editing program like Photoshop, and it may not work to delete the background from a photo or image with complex backgrounds. Start by taking a screenshot with Snagit, or upload an image from the File menu.

Images that have a white background, solid color, or high-contrast backgrounds work best. All you need to is click down on the fill color option in the Tool Properties and select the transparent fill. But sometimes you have an image with lots of different shades. If you have an image with lots of similar colors or gradients in the background you may end up with some bleeding around the icon, logo, etc. One thing you can do to remedy that is to adjust the tolerance of the fill.

One percent is the most strict and percent means it will pretty much wash out your entire image. You may have to play with the tolerance to get the right transparency level.

A color cube is a 3D color-lookup table that assigns a transparency value to RGB colors. For example, to filter out green from the input image, create a custom color cube with the green portion of its values set to 0. To specify a range of colors to exclude, model colors with an HSV hue-saturation-brightness representation. HSV represents hue as an angle around the central axis, as in a color wheel.

In order to make a chroma key color from the source image transparent, set its lookup table value to 0 when its hue is in the screen color's range. You will set transparency to 0 for this range in the color cube. To create the color cube, iterate across all values of red, green, and blue, entering a value of 0 for combinations that the filter should make transparent.

Refer to the numbered list for details on each step to the routine. Use a for-loop to iterate through each color combination of red, green, and blue, simulating a color gradient. Even though the color cube exists in RGB color space, it is easier to isolate and remove color based on hue. Input 0 for green hues to indicate complete removal; use 1 for other hues to leave those colors intact. To specify green as a hue value, convert its angle in the hue pie chart to a range of 0 to 1.

The green in the sample image has hue between 0. Your shade of green may differ, so adjust the range accordingly. The CIColor Cube filter requires premultiplied alpha values, meaning that the values in the lookup table have their transparency baked into their stored entries rather than applied when accessed. Apply the color cube filter to a foreground image by setting its input Image parameter and then accessing the output Image. The filter passes through each pixel in the input image, looks up its color in the color cube, and replaces the source color with the color in the color cube at the nearest position.

Chain a CISource Over Compositing filter to the color cube filter to composite a background image to the greenscreened output. The transparency in the colorcube-filtered image allows the composited background image to show through. The foreground of the source image now appears in front of the background landscape without any trace of the green screen.

Its not more effective. I need to achieve exact result what i have placed in above images. How to remove the background of image in iphone app? Changing the background color of a captured image from camera to white. Generally, as a rule of thumb, the more different the background color from all the other colors, the easier it is to split the image into fore- and background. In such a case, as Chris already suggested, it is possible to use a simple chroma key implementation.

A fully working code example can be found in this Github Gist. Unfortunately, your example does not stick to that rule of thumb. Since the foreground and background only vary in intensity it is difficult or even impossible to find a single global set of parameters for a good separation:.

So, if you cannot change the background of your images a more complicated approach is required. However, a quick and simple example implementation is a bit out of scope, but you may want to look into related areas of image segmentation and alpha matting.
