Previously introduced to the partners a portrait generation tool based on AI technology:LivePortraitIt can convert static photos into realistic dynamic portrait videos, and you need to upload a video along with the photo to realize the migration of expressions.
This is not really a customized emoji, it's the freedom of emoji. If there is a tool that can fine-tune the uploaded character's expression according to our instructions, then it can be called expression freedom and realize real expression customization.
Today, the tool is here, and the bottom line is also based on the LivePortrait The framework is realized, except that you can fine-tune the dynamics of the expression of different parts of the character's face by adjusting the parameters.
Okay, without further ado, let’s get started.
As usual, we'll go straight to the effect and then share exactly how it works!
First of all, we need to upload a character original picture, the left is the character original picture, and then we let the character blink an eye, the right is the effect of the picture, this effect can be it, the character consistency is still maintained perfectly!
Blinking while the pupil deviates to the right.
Pick another eyebrow.
Open your mouth again.
Change the shape of your mouth.
You can also adjust the angle of the character's head.
Not just anime characters, but real people as well.
Stickers can also be oh, as long as the face can be recognized can be oh! Animals can also be, but the effect is not so good!
Well, the effect is shown, let's see exactly how it works!
First of all, it is still necessary to prepare ComfyUI, the ComfyUI do not know the small friends can see listen to the rain public number top of the two articles.
Then search for: ComfyUI-AdvancedLivePortrait in the ComfyUI Manager, install and reboot.
The workflow is also very simple, there is only one node for manually modifying expressions, and you can see that there are a total of 12 management parameters for expressions.
We can take our time to debug the expression we want.
We won't introduce the emoji-related parameters, so just try it out for yourself, guys.
There's not much to say about "Original Expression Reference Intensity" and "Reference Expression Intensity", they are literal.
Let's skip the "sample_parts" and talk about the "application area coefficient", which is a parameter that enhances the expression-related parameters.
The left graph is 1.5 and the right graph is 2.5, and you can see that the right graph has a significantly greater range of motion than the left graph.
Next, let's talk about the "sample_parts" parameter, which brings us to another feature of this plugin that can migrate the expressions of the people in the photos we upload.
Another reference image can be added to our base workflow and used to migrate the facial expressions of the people in the reference image.
Select AII for "sample_parts" to migrate all expressions.
Only facial expression is migrated in "OnlyExpression", not the angle of the head.
Only the angle of the head is migrated by "OnlyRotation".
"OnlyMouth" is to migrate only the mouth expression of the character.
"OnlyEyes" is to migrate only the character's eye expression.
Reference image migration and expression parameters can be modified simultaneously!
In addition to the above two features, this plug-in also supports emoticon migration by uploading a video, and also supports the modification of the expression of the characters in the video, but before has been introduced to similar plug-ins, here will not do more introduction, this is on the partners to experience on their own, the workflow to listen to the rain will also be placed at the end of the article in the network disk.
Oh, by the way, this plugin supports real-time adjustment of parameters!
Click "More Options" on the right menu bar, select 1 for "Batch Number", then check "Auto Execution", and finally click "Add Cue Queue", as long as we modify a certain parameter, the emoticons will be automatically synchronized, without the need to repeat the point to generate, guys can try it.
Here only need the left mouse button to select the parameters we want to modify, the mouse left and right to move the parameters can be quickly modified oh!
Well, that's all for today's sharing, guys, go ahead and customize your emoji to achieve emoji freedom!
