1. A computer-implemented method for generating electronic signatures, comprising:
- recognizing, by a processor, a signing device in a first image taken by an imaging device, the recognizing comprising distinguishing the signing device from a surrounding environment based on pixel features of the signing device,wherein the signing device is a finger or a hand and wherein recognizing the signing device further comprises;
capturing, via the imaging device, the first image showing an object;
determining whether the object occupies more than a predetermined percentage of the first image; and
identifying the object as the signing device when it is determined that the object occupies more than the predetermined percentage of the first image;
capturing, via the imaging device, a plurality of image frames including the pixel features of the signing device;
identifying in the plurality of image frames, by the processor, pixels matching the pixel features of the signing device;
generating, by the processor, a second image including the identified pixels;
connecting, by the processor, the identified pixels within the second image to form at least one line drawing representing a signature;
detecting a change of gesture of the finger or hand;
generating a space, a punctuation mark, or a break in the at least one line drawing representing the signature based on the change of the gesture; and
displaying the at least one line drawing representing the signature in a graphical user interface.

17. A system for generating electronic signatures, comprising:
- an imaging device;
a display; a memory storing instructions; and a processor in communication with the imaging device, the processor being configured to execute the instructions to; recognize a signing device in an image taken by the imaging device, wherein the signing device is a finger or a hand; capture, via the imaging device, the image, the image showing an object; determine whether the object occupies more than a predetermined percentage of the image; identify the object as the signing device when it is determined that the object occupies more than a predetermined percentage of the image; control the imaging device to capture a plurality of image frames showing the signing device; identify, in the plurality of image frames, pixels matching recognized pixel features of the signing device; generate a first image including the identified pixels, wherein the first image is a combined image; connect the identified pixels to form at least one line drawing representing a signature; detect a change of gesture of the finger or hand; generate a space, a punctuation mark, or a break in the at least one line drawing representing a signature based on the change of the gesture; and displaying, on the display, the at least one line drawing representing the signature.
- an imaging device;

18. A non-transitory computer-readable medium storing instructions executable by a processor to cause the processor to perform operations for generating electronic signatures, the operations comprising:
-
recognizing a signing device in a first image taken by an imaging device by at least distinguishing the signing device from a surrounding environment based on pixel features of the signing device, wherein the signing device is a finger or a hand and wherein recognizing the signing device further comprises; capturing, via the imaging device, the first image showing an object; determining whether the object occupies more than a predetermined percentage of the first image; and identifying the object as the signing device when it is determined that the object occupies more than the predetermined percentage of the first image; storing the pixel features of a signing device, wherein the pixel features include shape and color information associated with the signing device; capturing, via an imaging device, a plurality of image frames including the pixel features of the signing device; identifying in the plurality of image frames, by a processor, first pixels matching the stored pixel features of the signing device; generating, by the processor, a first image including the identified pixels; and connecting, by the processor, the identified pixels to form at least one line drawing representing a signature; detecting a change of gesture of the finger or hand; generating a space, a punctuation mark, or a break in the at least one line drawing representing the signature based on the change of the gesture; and displaying the at least one line drawing representing the signature in a graphical user interface.
