Our algorithm should handle chemical images as generically as possible, Machine learning is certainly impressive, but it requires a high throughput In the next section, I go over our algorithm and how we are attempting to create the best CIR solution. Just have fun creating, and that is what iChemLabs excelsĪt. COPY AS IMAGE CHEMDOODLE LICENSESomething better in the ChemDoodle ecosystem where OSRA is not an ideal solution because (a) the license is notĬompatible, and (b) OSRA is a C++ tool, while ChemDoodle is Java. At iChemLabs, we also produce open source projects. Resources and contribute to those projects. I certainly encourage everyone to make use of open source May ask "This is good, why reinvent the wheel?". So this brings us to the present, and at iChemLabs we are building our own CIR solution. Machine learning (ML) has matured and become more applicable to solving problems. Providing an open source (GPLv2+) CIR solution, and is the most well known CIR solution today. Since the IBM Almaden paper, many other procedural CIR solutions have comeĪnd gone. Shape-based features, after which you build the chemical information from the ground up by interpreting those Their workīegan in 1988 and they outline a general procedure for a CIR algorithm: you break down the input pixels into Probably the earliest, most impactful literature for CIR algorithms is the Optical Recognition Of Chemical Graphics paper out of IBM Almaden in 1993. "Chemical Image Recovery" allows aĬhemist to get closer to the meaning we are attempting to recover the chemical information from an image. To a chemist, it will be very unlikely they know what you are referring to. If you say "Optical Structure Recognition" Same, "chemical" is replaced with "structure". Glyphs) already exists, and since we cannot call it Optical Chemical Recognition because the abbreviation is the It has beenĬalled OSR because an algorithm called Optical Character Recognition (OCR, for the computer recognition of In fact, a few solutions already exist, known in theĬheminformatics industry as Optical Structure Recognition (OSR) tools. You may also use the ChemDoodle Web ComponentsĬhemical image recovery is not a new concept. If you would like to try ChemDoodle's CIR function, you may use the File>Recover from Image. COPY AS IMAGE CHEMDOODLE ANDROIDThe android could also protect the chemist if safety We may even be able to produce androids for our labs with the ability to observe and understandĬhemical drawings and then complement scientists so they can get their work done faster. Picture of a molecule from a publication he/she is reading and immediately find more information from a chemical An assistive tool can be produced to help vision-impaired chemists. Students can simply point their camera at a chemical structure on a poster and get the associated You can have a program automatically catalog drawings from laboratory Input image, and the image on the right is the result of the CIR function in ChemDoodle 2D.Įven further processing on the recovered chemical drawing, optimizing a 3D structure using the MMFF94 force field and measuring the hydrogen bondīy recreating the chemical data originally lost in images, CIR makes it possible to produce For instance, take the following image of galanthamine. Information other than the defined pixels, and using a computer to recreate the original chemical data to beįurther. Original chemical data it represents is only realized in our minds.Ĭhemical image recovery (CIR) is the process of taking an image of a chemical drawing, with no provided Maybe we can enlarge it, copy it or print it, but the Just an image, we cannot do anything more than look at it. Molecules have been created for use in documents, databases, notebooks, websites, etc. Way to communicate information to visual creatures such as us. When we communicate as chemists, we often use images of molecules because a picture is the most effective New chemical image recovery features in ChemDoodle 2D Molecule drawings and communicate with a scientist. In this laboratory setting, an android is using its ability to see and understand New chemical image recovery function was included for automatically rebuilding chemical drawings from an image, We launched ChemDoodle 2D v11.4 on April 2nd, 2021.
