    We have a 25-30 page PSD mockup of an iOS app that we need developed. We have the working version of the Android already completed by one of our startup partners who is a software engineer. The mobile iOS application will have the ability to communicate with the SQL database through 3G/4G and WiFI connections in order to push and pull metadata. We have all of this code already written for the android app and for our website dashboard. I have attached a few JPGs of the PSD files we have for the iOS app project. please email me some questions. Obviously, cost is essential. We already have a quote received from a firm we have contracted with before, but their price point seems a bit high.

    I&quot;m looking to have an iphone app built with functionality similar to Tinder (but the information to choose/rate will not be other users). Users will see photos and descriptions pulled from a database and swipe to include or trash. All such user data will be captured in a database. It will also be linked and use information from the Facebook API to choose information to present to users. Initially the algorithm to code will not be too complex but there will likely be incremental business for coding of later improvements.I will be able to share more details only after an nda.I will provide- logo and app design (psd files)- wireframes (png or similar)- algorithm logic for all data processing (docx or similar)You will- create a database (please specify which and how)- code the app main functionality (and apply design)- code the data processing algo- code the link with Facebook API

    This application&quot;s main purpose is to help the user choose clothing that matches.The user (male) takes a picture of the article that he wants to find a match for and outlines the clothing so that the app can isolate it from the background. He then chooses the type of article it is (dress shirt, plain shirt, graphic shirt, dress pants, shorts, etc.), and the app uses a built in database to find him matches.The app should first return multiple types of clothing from which the user will choose which one he wants ( ex: user takes a picture of a red and blue t-shirt, the app then asks him if he wants shorts, bermudas, jeans, pants, etc.). After selection, the app will return a list of articles of clothing that can be worn with the one in the picture.If you choose to work on this project I will provide more specific information to clarify any doubts about the project.Budget is up for negotiation.

Users should be able to see an archive of messages that were sent/received. But messages can only be listened to (any many times as you want) within 24hours.Users can also allow others to &quot;follow&quot; them.

A new edge detection algorithm for flame image processing

I2MTC - IEEE Instrumentation and Measurement Technology Conference

Digital image processing is playing an increasingly important part in imaging based flame monitoring systems. A crucial step in flame image processing is to detect the flame edge, a dividing boundary between the area where there is thermo- chemical reaction and those without. The determination of flame edges is a precursor to flame image processing and measurement of flame parameters. Several known edge detection methods have been tested to identify flame edges but the results achieved are disappointing.
