A deep dive into CSS masking

If you need to use an image for your art, product, project, or any other reason, check out the Smithsonian's vast collection of Open Access images available under the Creative Commons Zero (CC0) license. I searched "cat," and it returned over 7,000 images, and every one I looked at was terrific.

CSS has a lot of pretty rad and powerful features for managing image rendering these days. Let’s leverage some of these, like aspect-ratio, object-fit, and object-position for when we need to use a single image in many different contexts.

This talk will take you through a novel Perl implementation of perceptual hashes for “similar image” searches. I'll start with the basics, if you don't know what a Discrete Cosine Transform is, you'll find out with a visual demo - no math required (although math is always encouraged!). After DCTs and p-hashing basics, I will go through the implementation’s new features that make it efficient and easy to integrate with our large MySQL-based image database.

At SpareRoom, the world’s largest roommate finding service, we handle tens of millions of images, mostly of customer rooms/properties. When tasked with adding an internal ability for a “similar image” search, I first looked at existing solutions and found out that some did not work as expected, while others were either slow or required changes to our infrastructure (mainly Perl, with the data - including the image index - on a large MySQL database).
In the end, I went with a solution initially based on Image::Hash, but with p-hashes reimplemented to fix collision issues and add speed (over 10x faster than pHash.org’s equivalent DCT-based hash). Then, I added features such as support for mirroring, as well as “index/reduced” hashes, in order to effectively use MySQL indices (and thus easily fit in our existing setup).
After an intro to the theory behind the DCT and perceptual hashes in general, I will discuss the abilites of this implementation and the experiences from developing and using it. The module will be released to CPAN before my talk, although the XS part responsible for the fast DCT calculation has been available for a while as Math::DCT.

1. Make your elements appear more defined
   Use Multiple Drop Shadows, or a very subtle border (just a shade darker than your actual shadow) around certain elements to make those elements appear a little sharper, more defined, and help avoid those muddy shadows.

2. Creating long-form content? Give 20pt, and up a try
   #18pt is sooo last decade.#

3. Your shadows are coming from one light source right?

4. Improve Contrast between Text and Images with a subtle, but simple Overlay
   Depending on where the text may be positioned over your image, you can either opt for a tried, and tested full image overlay, or a more subtle (bottom to top, or top to bottom) gradient overlay to achieve a simple contrast between the two elements.

Long-time Cloud Four readers will be familiar with Jason’s definitive series on responsive images. This article is meant as a shorter companion piece focused on the most common responsive image use case: resolution switching.

The Biodiversity Heritage Library (BHL), the world’s largest open-access digital archive dedicated to the natural world, is now offering more than 150,000 high-resolution illustrations for copyright-free download.

Creative Commons has officially launched CC Search, a search engine that indexes over 300 million images from 19 image collections, "including cultural works from museums (the Metropolitan Museum of Art, Cleveland Museum of Art), graphic designs and art works (Behance, DeviantArt), photos from Flickr, and an initial set of CC0 3D designs from Thingiverse." All of the indexed images are in the public domain and released under Creative Commons licenses--meaning the images are generally free to use in a non-commercial setting.

A look at the colour trend taking the world by storm
The modern web is full of colour-from subtle to bright ‘in your face’ tones. I’ll be taking a look at the latter. Meet duotone-the hottest colour style of 2016.

Pure duotone & other tonal groupings

Love it or loathe it-duotone is everywhere right now. As the name suggests, duotone is an image made up of two colours, usually vibrant shades are used but you can select more subdued ones if you wish.

Convert any major image format into a highly optimized JPEG
Drag your image into the dropspace below, and we'll convert it into a progressive JPEG
and then optimize it using an advanced JPEG optimization technology.

Speaking about using sharp angles and shapes, Tokyo-based illustrator Jun Takahashi uses this technique to create geometric sports characters.
