Automatic map stitching

Nowa­days there are many HTML5-based map ser­vices, but typ­ically they don't of­fer any ex­port func­tion­al­ity. To cre­ate a full view of the de­sired re­gion, one can ei­ther zoom out (and lose map de­tails) or take many screen­shots of dif­fer­ent lo­ca­tions and man­ually stitch them to­gether. This pro­ject can au­to­mat­ically load all stored screen­shots, de­tect the map, crop rel­evant re­gions, de­ter­mine im­ages rel­ative off­sets and gen­er­ate the high-res out­put with zero con­fig­ura­tion from any map ser­vice.

Real-time car tracking and counting

From my of­fice win­dow I've got an un­blocked size-view to the Ring Road I (Kehä I) in Es­poo, Fin­land. It is one of the bus­iest roads in Fin­land, hav­ing up-to 100.000 cars / day. I wanted to cre­ate a pro­gram which would re­ceive a video feed from a we­bcam and would pro­cess im­ages in real time on com­mon hard­ware.

Coin recognition algorithm

I de­vel­oped a coin recog­ni­tion sys­tem which can rec­og­nize eight dif­fer­ent groups of coins. The used set is all five coins of Sin­ga­pore, but a few cat­egories can­not be dis­tin­guished from each other with­out knowl­edge of the coin's size in re­la­tion to oth­ers.
