    Lithuanian Fraktur OCR Training
    6 วัน left
    ยืนยันแล้ว

    I have a run of Lithuanian newspapers printed in Fraktur between 1820 – 1920 and I am already getting fair results by applying Transkribus’ Danish 19th-century Gothic model. I now need a custom model that properly understands both headlines and body text so the character error rate drops to an acceptable level. You will receive a set of high-resolution scanned pages that can serve as ground-truth material. During training we must pay special attention to modernising the historic glyphs: the Fraktur w needs to be normalised to v and the model must reliably output š, č and ž. If you have a proven workflow for creating layout‐ground-truth, running HTR+ experiments, and iterating on confusion pairs, that is exactly what I’m after. Deliverables • A trained Transk...

    I run Odoo 19 on the free (community) build and would like it to talk seamlessly with the Intui platform. The goal is hands-off order management: as soon as an order appears in Intui it should land in Odoo, and if that order is changed or cancelled later, the same change must show up in Odoo in real time. Beyond the order itself I also need the integration to pull across the related customer record and keep product inventory levels accurate in both systems. Whenever a sync problem occurs I want an automatic email alert so I can react immediately; silent logging alone isn’t enough. I expect you to deliver an installable Odoo 19 module (Python, XML, possibly JavaScript for UI tweaks) plus clear setup instructions and a brief test plan that proves: • new Intui orders create corr...

    I have raw footage that needs to be shaped into a polished social-media piece for both Instagram and YouTube. The final cut should feel professional and clean—think sharp pacing, accurate color correction, tasteful motion graphics, and on-brand typography rather than flashy effects. Please handle: • Selecting the strongest takes, trimming for tight storytelling • Color grading and light audio cleanup so everything looks and sounds consistent • Simple lower-thirds or captions that remain readable on mobile • Two exports: 9:16 for Instagram Reels and 16:9 for YouTube, both in high-resolution MP4 Deliver the project files (Premiere Pro or Final Cut Pro preferred), plus the final renders, ready to upload with no additional tweaks.

    I run Odoo 19 and the built-in Sales module is lagging behind the rest of the system. The goal is to bring every part of that module—models, views, business logic and reports—up to Odoo 19 standards so all Sales workflows function smoothly again. Scope • Update Python code to the current ORM and API conventions • Refactor XML views, menus and QWeb templates that throw warnings or break under the new framework • Ensure existing quotation flows, order confirmations and invoicing hooks keep their original business rules • Resolve any deprecations or security rule mismatches introduced by the core upgrade • Perform end-to-end testing inside my live Odoo 19 environment and supply a brief technical changelog Acceptance The upgraded module must i...

    I need a browser-based back-office portal that can speak fluently to both Verifone Commander and Gilbarco Passport systems running in our forecourts. The goal is to centralise inventory, capture every transaction in real time, and give my staff role-based access without relying on the vendor-supplied desktop tools. Your experience configuring Verifone and Gilbarco is essential; the project will involve working with their XML/JSON feeds, pollers, and any available APIs to pull price books, tank levels, and sales data into a single PostgreSQL or MySQL store (I am open to your recommendation). From there, the web UI—preferably built with a mainstream framework such as React, Vue, or Angular—should present dashboards for stock levels, live transaction logs, and straightforward scr...

    I’m spending far too much time re-typing purchase vouchers into Tally when everything is already organised in Excel. I need a small utility that reads those spreadsheets and posts each row as a purchase entry in my Tally company, with all taxes, supplier details and inventory lines carried over exactly as they appear in the sheet. You are free to choose the most efficient route—Tally XML import, ODBC, TDL, or a Python/.NET bridge—so long as the final result is a one-click (or near one-click) process that any non-technical staff member can run on a Windows machine. Deliverables • Executable tool or script with a simple UI or clear command-line instructions • Mapping configuration so I can point new spreadsheet layouts to the correct Tally fields without cod...

    • Description The objective is to create a prototype that sends our XML string via AS4 to a destination URL. You can start with <test>dummy</test> for now, but we will test with real xml. You will need to sign with the internal private key certificate and encrypt with the external public key certificate. The other side will decrypt with their private key certificate and verify our signature with our public key certificate. We will give you the certificates. You will then listen to our URL. They will send an async message 10-15 minutes later. We will give you access to our VPS, so the DNS will be routed to the VPS. You will need to verify their signature with their public key and decrypt the message with our private key. Success metrics are that the message is successfull...
