This paper presents a novel algorithm to generate micrography QR codes, a novel machine-readable graphic generated by embedding a QR code within a micrography image. The unique structure of micrography makes it incompatible with existing methods used to combine QR codes with natural or halftone images. We exploited the high-frequency nature of micrography in the design of a novel deformation model that enables the skillful warping of individual letters and adjustment of font weights to enable… 
The Nested QR Code
TLDR
Construction methods for generating the proposed nested QR code with high decoding robustness are presented, and experimental results verify the feasibility of the proposed method.

TLDR
Though based on approaches for addressing the classic problem of algorithmic two-dimensional bin-packing, aesthetically pleasing results are achieved through the incorporation of a small set of rules to guide the layout.
Q UALITY I NCREASES AS THE E RROR R ATE D ECREASES
TLDR
This paper proposes an approach to the design of processes and software that aims at decreasing human and software errors, based on the natural relationship between quality and error rate, increasing the latter as the error rate decreases.
Quality increases as the error rate decreases

Artistic QR Code Embellishment
TLDR
A novel framework for embellishing a standard QR code, to make it both attractive and recognizable by any human while maintaining its scanability, is proposed and yields lower data error than previous global transformation techniques.
QR Images: Optimized Image Embedding in QR Codes
This paper introduces the concept of QR images, an automatic method to embed QR codes into color images with bounded probability of detection error. These embeddings are compatible with standard
Halftone QR codes
TLDR
This work builds a pattern readability function wherein it learns a probability distribution of what modules can be replaced by which other modules in QR codes, and expresses the input image in terms of the learned dictionary to encode the source text.
Efficient QR Code Beautification With High Quality Visual Content
TLDR
A two-stage approach to generate QR code with high quality visual content based on the Gauss-Jordan elimination procedure and the experimental results show that the proposed method substantially enhances the appearance of the QR code and the processing complexity is near real-time.
Appearance-Based QR Code Beautifier
TLDR
This work makes QR code from machine decodable only (i.e. standardized random texture) to a personalized form with human visual pleasing appearance and expects the proposed QR code beautifier can inspire more visual-pleasant mobile multimedia applications.

TLDR
This paper proposes a system for decorating 2-dimensional barcode with some illustrations inside the code without detracting machine-readability and stored information and solves the task by using real-coded genetic algorithm.
Calligraphic packing
TLDR
A solution to the "calligraphic packing" problem based on dividing up a target region into pieces and warping a letter into each piece is developed and an energy function that chooses a warp that best represents the original letter is defined.
