Watermarked image replacement tool (image processing) (50$)

Hello! Thank you for having interest in this topic. Long ago, I have tried this task by myself. sometimes it seemed like it could be solved very easily, but the performance from my tool was quite horrible. so here I am to compensate my lack of ability to make a good 'image watermark manipulation' tool. * if you have interest in similar topic previously, or made similar work, please let me know after reading notes down below. Essential Feature note 1: Should be able to detect watermark automatically on sample images. (should demonstrate by your own image set sample) Essential Feature note 2: Should be able to remove watermark in the sample image. question Feature note 3: should be able to input new watermark inside of the image. condition 1: This tool should be done in 100% script and need to be done 100% programming way. such as Python. Any implemented 3rd party payed software can not be adopted. condition 2: whether you made this tool or not is not important. I also have experience of making its tool myself but I'm posting this project again just to look for actual better performing tool rather than mine. the performance itself is the higest consideration in this project. condition 3: (important) please apply only if you have done similar projects so you can show me the screencaped examples of your tools right away. or else it would be taking too much of time just trying to make this tool, and if the performance is low, I wouldn't release any milestone or money. please get notified this. condition 4: after the work is done, please show me 10 example cases so I can check its quality. condition 5: after you showing me your tool's example results as condition 4, I can cross check bringing examples from my backgrounds. to check its validness condition 6: (important) milestone will be released only after meeting satisfactory of condition 4, condition 5. condition 7: other practical recommandation or suggestion would be welcomed. Thank you for reading! Have a good day and bid me if you think you can build one. Anytime ! And I am willing to respond very quickly to explain more what I exactly need. also, if you can really make it out well this time in this project, I will promise to carry out further projects with you. Thanks alot.
